Kinghelm Sales Deputy Director Peng Huisheng: A Hakka in Shenzhen, Staying True to His Original Aspiration Through Hard Work
2026-08-03
"Stay clear-headed, self-disciplined, know when to advance and when to retreat, and understand what you gain and lose." — This is the striving motto of Peng Huisheng, Deputy Director of Sales Department II at Kinghelm. He joined Kinghelm in November 2022, starting as a grassroots salesperson, and was promoted to Deputy Director of Sales Department II in May 2026. Over four years in sales, his performance has lived up to his name "Huisheng" (meaning "bringing life") — always surprising and inspiring. Since the launch of the "Dragon-Tiger Warrior" incentive system at Kinghelm and Slkor in March 2026, Peng Huisheng secured third place in April. He said, "I’m still pushing hard for the champion and runner-up spots. I will steadily build my foundation and strive to achieve better rankings soon." General Manager Song Shiqiang stated that Kinghelm commends excellence and advocates for outstanding performance, and will give maximum support to employees who show drive, determination, and the ability to get things done.
Peng Huisheng, Deputy Director of Sales Department II, Kinghelm
Peng Huisheng, born in the 1980s, is a Hakka from Meizhou, Guangdong. His name "Huisheng" carries an auspicious meaning — evoking new life, festive harmony, and enduring vitality. Peng shared, "Huisheng embodies my family’s two great hopes — that I can earn a living and also live a free and happy life, never worrying about subsistence and always living comfortably." Speaking of his hometown Meizhou, Peng said with warmth, "Whenever I have free time, I go back to Meizhou. This ‘World Capital of the Hakka’ is blessed with beautiful mountains and rivers. According to the Guangxu Jiaying Prefecture Gazette, Meizhou got its name from the local ‘Mei Peak’ mountain and ‘Mei Stream’ water. The familiar Hakka enclosed houses — a form of clan settlement integrating residence, ancestral worship, and education — are known as the ‘Ancient Roman Castles of the East.’ Hakka specialties like stuffed tofu, Mei Cai Kou Rou (braised pork with preserved mustard greens), and salt-baked chicken carry a thousand years of culinary heritage, and they are our way of savoring happiness. The village carnival every New Year’s Eve, with deafening gongs and drums, fills the air with festive spirit. My father plays the big drum while I strike the gong — our unspoken father-son bond is renewed and strengthened through cultural preservation and inheritance. Most importantly, the Hakka virtues of loyalty, honesty, and pragmatism are the very foundation of my character."
When asked about the origin of the gong-and-drum custom, Peng recalled, "The village has a wonderful New Year atmosphere. Every New Year’s Eve, after dinner, villagers naturally come out and gather together to chat and catch up on family news. My father has always been the village drummer — it’s a tradition passed down from the older generation. When he beats the drum, he seems to radiate energy and brilliance. I learned to strike the gong by consciously joining in and passing it on each New Year’s Eve, because inheriting our culture and sustaining our national roots is the mission of every generation."
Peng Huisheng, Sales Elite at Kinghelm
Peng Huisheng has been in sales at Kinghelm for four years. He got started quickly, performed well, and has consistently achieved remarkable results as if on a winning streak. When asked about his secrets to continuous big orders, he humbly said, "It’s all thanks to Kinghelm’s platform, brand, and team. Kinghelm is my first stop in transitioning to sales, and I am grateful to the company for its training and trust, allowing me to move forward steadily on a path of integrity, pragmatism, and positive hard work. I also thank my past experience — right after graduation, I came to Shenzhen and learned many practical skills, such as working as a mobile phone after-sales engineer for over ten years. Because Kinghelm’s ‘Kinghelm’ brand products are well-known and widely used in smartphones, my decade-plus of phone repair experience proved to be a perfect match. It helped me settle in quickly at Kinghelm, deepen my product expertise, and solve customers’ pain points, making transactions smoother and more reassuring for clients."
When asked, "Beyond experience, how else can you drive sales?" Peng offered practical advice based on his own work: "First, uphold your bottom line. As a son-in-law of a Chaoshan family, I have participated in Chaoshan ancestral rites and traditional banquets. Through genuine contact, I have been deeply influenced by the Chaoshan people’s principles of keeping promises, valuing relationships, and treating others with warmth — these are the bottom lines I adhere to in my career. Second, mindset comes first. Focus on solving problems rather than dwelling on past gains or losses. Dedicate your mind to serving customers and mastering products — this stabilizes your mindset and drives continuous improvement. Third, invest in daily effort. Deepen your understanding of product specifications and industry applications, engage with customers to accumulate hands-on experience, and constantly review and summarize. Over time, your professional competence will naturally become solid."
Peng Huisheng, Deputy Director of Sales at Kinghelm: Responsibility and Commitment Can Overcome All Difficulties
After being promoted to Deputy Director of Sales at Kinghelm, Peng admitted, "My focus has shifted from personal client acquisition to team collaboration and shared success. Mentally, I carry an added sense of responsibility — to grow the team together and make it stronger." To fulfill this responsibility, Peng integrates General Manager Song Shiqiang’s leadership training with practical work to empower the team for win-win development; he regularizes his personal sales sharing into a replicable routine, mainly exchanging real combat experiences and customer challenges to promote mutual learning and improvement across the team; and he leverages exhibitions as a key channel for efficient client outreach, realizing the declaration of "Kinghelm Connects the World." Take the 2026 electronica Shanghai, which Peng participated in, as an example. To ensure smooth and efficient exhibition interactions, he invited target major clients in advance for on-site meetings, prepared samples, product materials, and promotional items, organized RF product parameters, and planned communication scripts ahead of time.
"The most important thing in sales is proactivity," Peng emphasized. He noted, "As a deputy sales director, I participate in interviewing new recruits and always ask candidates, ‘Are you highly motivated and proactive?’" He further explained, "In sales, you have to put aside so-called pride. If you don’t understand something, ask proactively; if you don’t know, learn proactively. Treat customers like you would court a girlfriend — if they don’t respond, keep engaging persistently; if problems arise, find solutions; don’t give them the cold shoulder or force them to yield. Also, remember to send greetings during holidays. With long-term sincere maintenance, you can steadily build up major client resources."
Company Profile of Kinghelm
Sales is like sailing against the current — if you don’t advance, you retreat. Looking ahead, Peng envisioned, "I wish Kinghelm continued vigorous growth. I thank my family for their understanding and companionship. I hope to stay true to my original aspiration and keep improving — growing with the team at work, continuously creating value, and deeply cultivating the RF connector field to sustain Kinghelm’s reputation and quality for the long term. In life, I want to spend more time with my family and participate in my children’s growth, practicing the belief that ‘everything is for a better life,’ and achieving a balanced life with both career and family fulfillment."
Song Shiqiang on Strategy: Highlights from the 2026 electronica Shanghai Dialogues
2026-07-21
In early July 2026, Kinghelm and Slkor made a high-profile appearance at 2026 electronica Shanghai, sending a team of over 30 people and occupying a 72-square-meter booth with a technologically striking and visually powerful layout. As a thought leader in Huaqiangbei, General Manager Mr. Song Shiqiang was invited to the eefocus Executive Dialogue live studio, participated in interviews and live streaming with Zhixin Suge’s "GESA Chip Shines East," and contributed to a special written interview with Hc360.com – all of which drove strong exposure and deep brand engagement for "Kinghelm" and "Slkor." At electronica Shanghai, Kinghelm and Slkor showcased their capabilities alongside international giants such as TE Connectivity, Amphenol, Molex, Hirose, Infineon, Texas Instruments, STMicroelectronics, and onsemi, as well as outstanding domestic players including Electric Connector, Changjiang Connector, Silan Micro, China Resources Micro, and Jiejie Microelectronics – competing, exchanging ideas, and growing together.
Song Shiqiang on Strategy I: "Slkor: Chinese Semiconductors Going Global"
Mr. Song Shiqiang, founder of Slkor Semiconductor, engaged in a compelling discussion with Mr. Li Jian, senior industry analyst at eefocus, on the theme "Slkor: Chinese Semiconductors Going Global."
Slkor Semiconductor founder Song Shiqiang (left) with eefocus senior industry analyst Li Jian
Chinese power semiconductors are transitioning from the "chip shortage" dividend period to the deep waters of market competition. As global chip supplies normalize and international brands cut prices to recapture market share, the window for domestic substitution is narrowing. In this context, Mr. Song shared the "disruptive innovation" path he has practiced throughout his entrepreneurial journey.
Mr. Song Shiqiang (left) at the eefocus live studio
Song pointed out that while cutting-edge technologies like silicon carbide have great promise, their R&D and commercialization cycles are lengthy, making them less optimal for startups. Slkor chose to start with products such as MOSFETs, IGBTs, and bridge rectifiers – technologies that are relatively mature, have lower entry barriers, and shorter cycles, enabling rapid cash flow generation. Later, the company added ESD protection diodes, TVS transient suppression diodes, power management ICs, and other analog products. This strategy reflects a deep understanding and flexible application of the economic principles of "disruptive innovation" – which involves breaking through from niche markets to the core, penetrating and gradually displacing high-end products from the low-end, ultimately achieving sustained innovation and breakthroughs.
At the same time, Slkor and its sister company Kinghelm have built a unique dual-brand synergistic ecosystem. Mr. Song recalled that the initial rationale for running the "Kinghelm" and "Slkor" dual brands was to diversify risks from market fluctuations and public listing. Unexpectedly, both brands have flourished, and cross-orders from customers have generated a "1+1>2" ecological reuse effect – with upfront investments in brand penetration, sample delivery, employee training, and internal knowledge engineering paying off in one go.
Song Shiqiang: We want to let time verify our products, our brand, and the value of our team
Song attributes the competitiveness of Chinese semiconductor companies to two factors: first, the diligence of the Chinese people, with sustained positive labor input driving rapid product iteration; second, the maturity of the domestic industrial chain, where technology and market mutually reinforce each other in a virtuous cycle. However, he also clearly recognizes that competition is intensifying. In a weak economy, massive capital has flooded into the electronics information sector, and the growth in industry output value lags far behind the influx of speculative capital. "Competing on price, efficiency, and response speed" has become the norm.
Currently, Slkor is evolving from "product going global" to a new stage of "comprehensive globalization," aiming to secure a prominent position in the global power semiconductor landscape. Song remarked: "Our company has a rule: we don’t do things that can be done by three to five people, nor things that can be done in three to five years. We want to let time verify our products, our brand, and the value of our team. This is also our corporate firewall."

Song Shiqiang: Kinghelm’s goal is the stars and the sea – to become a publicly listed company representing a national brand!
"Kinghelm" conveys a powerful sense of strength, rich in meaning and depth. "Kinghelm – Connecting the World." In 2007, Shenzhen Kinghelm Electronics Co., Ltd. set sail from Huaqiangbei, Shenzhen. Its technical team, rooted in Tsinghua University and the University of Electronic Science and Technology of China, has attracted outstanding professionals, deepened its expertise in microwave RF technology, and established new technology research institutes in collaboration with universities. Today, it has grown into a nationally recognized high-tech enterprise, industry-leading in the R&D, production, sales, and technical services of RF microwave signal transmission products and comprehensive solutions. High technology, superior quality, and safety are our unremitting pursuits.
Mr. Song explained that Kinghelm’s English name combines "King" (meaning sovereign) and "helm" (the rudder that steers direction and navigates storms). "Kinghelm" signifies ambitious goals, fearlessness in the face of challenges, and the pursuit of a royal path – embodying the Eastern wisdom of "Inner Sage, Outer King" and "Great Virtue Sustains All Things" advocated by Mr. Song. "Kinghelm – Connecting the World." Since its founding in 2007, the company has successfully shaped the "King’s Rudder" brand image, achieving remarkable success in the Beidou satellite navigation and positioning systems and related products, leading industry trends, and emerging as a "leading enterprise" in the sector. Meanwhile, its market share in the connector segment continues to grow, and the "Kinghelm" brand enjoys influence and reputation in international markets.
Mr. Song emphasized that Kinghelm’s slogan is "Kinghelm – Connecting the World." "We strive to produce excellent products, capture more market share, and serve more customers. Kinghelm’s corporate vision is to make our antennas and connectors serve a broad customer base, facilitating smooth global communication and social harmony. Products are the vessel; culture is the soul. Culture empowers products with a 'brand soul.' Our goal is the stars and the sea – to become a publicly listed company representing a national brand, and to bring our 'Inner Sage, Outer King' corporate culture and 'Kinghelm' brand products to the world. A public listing signifies success for both our individuals and the company, and enables our employees to share more in the rewards. It is precisely our people-centric philosophy – 'good work leads to a good life' – and the organizational and behavioral mechanisms built upon it, combined with ensuring that knowledge density, talent structure, systems, processes, and mechanisms efficiently complete the business loop, that have enabled Kinghelm to achieve high efficiency, greater rewards for colleagues, an ever-growing team with stronger cohesion and commitment, and rapid and steady development even during industry downturns."
CGC · Champion Strategy Visits Slkor
Song Shiqiang: Slkor aims to become one of the world’s most competitive semiconductor companies
"Slkor–Chips Driven future." Since its founding in 2015, Slkor has risen as a formidable contender. Its technical backbone comes from Tsinghua University and Yonsei University in South Korea, leading the company with new materials, new processes, and new products, and mastering world-leading third-generation semiconductor silicon carbide power device technology. "Slkor" – trust is the foundation, righteousness is the soul; trust is inscribed in the vessel, righteousness is fulfilled in action. This conviction drives our continuous exploration of cutting-edge semiconductor technologies. Our friends are spread across four seas, and our products reach five continents. Together with its sister company Kinghelm, Slkor has formed a high-speed development model driven by the interactive push of the "Kinghelm" and "Slkor" brands and products, deeply integrated with China’s booming semiconductor chip market. We treat our colleagues with care, develop products with dedication, serve our customers with heart, and hope to make the future better through our products and technologies.
Song noted that ultimately, business success comes down to culture. Taking the 2026 electronica Shanghai as an example, over 2,000 top exhibitors from home and abroad competed on the same stage – from booth design and corporate videos to team core competencies and individual best performances. On the surface, it was all about selling products, finding customers, and boosting sales, but in essence, it was a showcase of culture, strength, and depth – and also an opportunity to train the team and empower each employee. These are the "soul" elements. What deserves reflection is how to effectively present team spirit, company strength, brand influence, technological and product leadership; how to disseminate corporate values, vision, and mission efficiently and accurately through corporate videos; and how to understand the essence of service, customers’ latent needs, and differentiated competitive strategies – these are the gaps between Chinese companies and multinational giants in the process of globalization.
Song particularly emphasized that Slkor’s global strategy follows a path of specialization, differentiation, and high-end development, consciously resisting "involution-style" competition, and surviving and growing amidst multiple constraints. It has become one of the best-developed companies in China’s semiconductor sector. This differentiated competition means continuous innovation, continuous deployment, continuous self-pressure, and continuous self-breakthrough. Only thus could Slkor seize the opportunity at 2026 electronica Shanghai to showcase its strength, creativity, corporate culture, and attention to detail to peers and partners worldwide. Observing over the past few days, I found that the Slkor and Kinghelm booth attracted more foot traffic, energy, and visitor flow than neighboring booths – because our team arrived earliest and most completely, everyone prepared thoroughly upon arrival, kept working hard, helped each other, and spontaneously reviewed and summarized experiences during breaks. Improving a little every day, staying focused on our goals – it is this spirit that enables Slkor Semiconductor to excel in products, business, and every detail, and has now set it on a path of high-quality development, solidifying the foundation for its public listing.
Song Shiqiang on Strategy III: "The Counter-Attack and Breakthrough of Domestic Brands"
Slkor’s article featured as the headline in Hc360.com’s "Chip News Top Stories" column
As a thought leader in the electronics information industry, Mr. Song Shiqiang has attracted widespread attention. Slkor’s press release "See You Next Year | Slkor’s Highlights at 2026 electronica Shanghai" was featured as the lead story in Hc360.com’s "Chip News Top Stories" column. Excerpts from Hc360’s written interview with Slkor’s Song Shiqiang were included in the article "AI Computing Power 'Consumes' Capacity, Power Devices Tight Across the Board". In light of the market situation where "AI data center deployments are driving strong demand for power switches and ICs, leading to shortages," Mr. Song’s core views, corporate strategy, and trend assessments are as follows:
Slkor founder Mr. Song Shiqiang
Core View: For MOSFETs and IGBTs, due to capacity squeezes at foundries and OSATs from other higher-margin products, lead times have lengthened this year, with occasional shortages.
Corporate Strategy: Domestic power devices are evolving from initial "device replacement" to comprehensive "solution competition." This year, the adoption of Slkor’s SiC MOSFETs and other products at the customer end has accelerated, driven by growing recognition of the domestic "Slkor" brand. However, due to intense competition among peers, significant volume growth has not yet materialized.
Trend Assessment: In domestic power device production, domestic brands are gradually squeezing out import brands – particularly evident in low-end products, with signs of loosening in high-end products as well. This assessment provides a positive signal for the trend that "the upward cycle will continue at least through 2027," confirming the explosive momentum of domestic substitution acceleration. The industry rule of "disruptive innovation" applies here as well.

Mr.Cen Jianjun, General Manager of CEN Ningbo Jinshan New Materials Co., Ltd.
Jinshan means completing today's tasks today—a homophone for "golden mountain" or "silver mountain" —and it requires overcoming challenges like climbing a mountain. The development of the polyimide industry remains a long and arduous journey. In this issue of King Helm (www.kinghelm.com.cn), our reporting team visited Ningbo Jinshan New Materials Co., Ltd. (china-polyimide.com), a national key enterprise recognized as a "Little Giant" in specialized, refined, distinctive, and innovative industries, and conducted an exclusive interview with its founder, chairman, and general manager, Mr.Cen Jianjun. He vividly embodied the Tsinghua spirit of serving the nation through scientific research, having dedicated 29 years to advancing China's polyimide industry. He has mastered the core technology for producing high-performance polyimide films, developed various differentiated polyimide film products, and implemented the strategic vision of "playing a supporting role by developing unique polyimide products that domestic competitors cannot produce, thereby addressing customer pain points." Cen Jianjun emphasized that achieving high-quality development of China's economy necessitates first resolving the bottleneck in high-end materials within the industrial sector. Polyimide (PI) is one of the best organic polymer materials in terms of comprehensive performance, hailed as the "golden film" and "golden plastic." It boasts advantages such as resistance to extreme temperatures, high insulation, strength, radiation resistance, self-extinguishing flame retardancy, halogen-free environmental friendliness, excellent mechanical properties, and ease of recycling, making it a core material for strategic emerging industries including AI computing power, advanced semiconductor packaging, aerospace, gas separation, flexible displays, and new energy vehicles. The polyimide (PI) industry is a quintessential capital-and technology-intensive sector characterized by high technological barriers, substantial investment requirements, and significant added value. The global market exhibits an oligopolistic structure dominated by premium products and profits. Mr.Cen Jianjun stated: "Foreign companies have imposed significant technological constraints on polyimide development in many aspects, while China has long faced challenges of 'excess low-end production and reliance on imported high-end products.' CEN Jinshan is committed to advancing into the high-end product segment, continuously innovating and launching differentiated PI products to overcome the technological bottlenecks in high-end polyimide film materials, break foreign monopolies, and address the shortcomings within the domestic industry."

Steven Cen, whose English name "Steven" derives from Latin and Greek meanings of "crown" or "flower crown," graduated with a bachelor's degree from Tsinghua University in 1992. He recalled: "Born in 1969, I was admitted to Tsinghua University in 1987 from Yuyao High School in Ningbo, Zhejiang Province, enrolling in the Department of Hydraulic and Hydroelectric Engineering, majoring in Hydropower Engineering Architecture. During my five-year undergraduate program, what impressed me most was how outstanding my classmates were. I faced all challenges courageously; although some efforts ended in failure, I refused to be defeated—my inherent refusal to give up and growing resilience after setbacks are gifts that Tsinghua has bestowed upon my life. The aspiration to' integrate personal development into collective endeavors and closely link personal achievements with those of the university and the nation' has shaped the direction of my life."
Since its establishment in 1911, Tsinghua University has embodied the spirit of "redressing national humiliation and dedicating itself to the motherland." The "Tsinghua Spirit" —referring to the patriotic sentiment and commitment to serving the country among its members—was deeply rooted in this ethos. After graduating from Tsinghua University in 1992, Cen Jianjun was initially assigned to a water resources and hydropower design institute. Inspired by Deng Xiaoping's Southern Tour speech, he decisively left the government sector to pursue entrepreneurship. Seizing opportunities of the era, he joined one of the most innovative real estate and foreign trade companies of the time, leveraging its wealth-creation potential and contemporary relevance. Starting from a sales position with access to extensive market information, he learned through practical experience, customer insights, and market trends. Later, he independently operated foreign trade businesses and established factories, but faced closure due to inadequate quality control. Cen Jianjun summarized this experience: "Product quality is the lifeline of an enterprise—the foundation for market competitiveness and the guarantee of sustainable development. It determines an organization's fate; without quality, there can be no growth."
The academic rigor and keen insight of Tsinghua University alumni once again opened the door to entrepreneurship for Cen Jianjun. He recalled: "When the internet first emerged in 1996, many people doubted its potential. Yet I recognized the immense business opportunities it held. I began using the internet to gather information, connect with clients, and conduct trade. It was under the impetus of 'Internet+' that I delved into materials science in 1997, gradually deepening my expertise through practical trading experiences. In 1998, the call to accelerate the development of private enterprises inspired me, but the experience of factory closures made me more cautious and focused. After thorough preparation, I returned to entrepreneurship in 2001 by establishing my own factory, strictly controlling product quality from then on." For over two decades, Mr.Cen has dedicated himself to the polyimide industry, leading his team to develop high-end polyimide products competitive with international standards. He consistently embodies an innovative spirit of self-improvement, striving to overcome technical bottlenecks—a true reflection of the dedication characteristic of Tsinghua researchers. As chairman and senior engineer of Ningbo Jinshan New Materials Co., Ltd., he has served for years as vice president and secretary-general of the Ningbo Tsinghua University Alumni Association, currently holding the position of executive vice president, and is also a member of the Tsinghua Entrepreneurs Association (TEEC).
