Editor’s Note: In Chaozhou, the tide embraces all rivers. In this issue, reporters from Kinghelm ( www.kinghelm.net ) visited Shenzhen Meilong Electronics Co., Ltd. ( www.szmeilong.com ) for an exclusive interview with Mr. Chen Haisheng, founder and chairman of Meilong Electronics, Yougan Network, and AI Machine Era. A Chaozhou-born entrepreneur of the 1970s generation, Mr. Chen has spent three decades building his career—27 years deeply rooted in Shenzhen’s Huaqiangbei electronics hub and nine years contributing to the development of the Qianhai area. He founded the globally recognized resistor brand SUPEROHM, the 2025 “National Brand Light” initiative AI Machine Era, and the full-range, self-operated electronic components platform Yougan Network. Today, these three enterprises employ more than 600 people worldwide. During the interview, we also had the opportunity to meet Mr. Chen’s son, Chen Qiyue—a poised and impressive young man in his twenties who has studied overseas for six ye...

While groundbreaking innovations like artificial intelligence (AI) have surged forward in recent years, they have yet to ignite the kind of sweeping economic boom seen in a new Kondratieff Wave. Meanwhile, global markets face headwinds from geopolitical tensions, escalating tariffs, and fierce competition in increasingly saturated sectors. In today’s high-stakes landscape, even the slightest misstep can jeopardize a company’s position. Amid this turbulence, SLKOR ( www.slkoric.com ) and Kinghelm ( www.kinghelm.net ) defied the odds—achieving a remarkable 80% compound growth rate in 2024 . Both brands not only expanded their market footprint but also earned growing international recognition as rising leaders in the electronics and semiconductor industries.   At the helm of SLKOR and Kinghelm is Mr. Song Shiqiang , a visionary entrepreneur, grassroots economist, and cultural researcher known for his in-depth studies of Huaqiangbei , China's iconic electronics marketplace. Mr. Song...
