Serenity’s A-share debut with Aleabitoreddit is here, with the first stock being Green Harmonic. This is a tech company based in Suzhou. The founder is Zuo Yuyu, and his brother Zuo Jing is the second-in-command. The younger brother studied technology in Japan and previously ran a hardware processing factory. The older brother was formerly the deputy director of the Suzhou Xiangcheng District Tax Bureau, holding a Level-County official rank. He later left government service to join his brother’s company, and they’ve been running it together ever since. Last May, the brothers cashed out approximately RMB 700 million, selling at a阶段性 high point, after which the stock price subsequently doubled. The company’s products are quite strong. It’s clear Serenity did thorough research. Green Harmonic holds the top market share in China and second globally for harmonic reducers. Its customers include China’s leading robotics brands such as Unitree, UBTECH, and AgiX. It also collaborates with DeepSeek on joint R&D efforts, primarily developing joint modules for humanoid robots, along with some limited overseas business, such as participation in the Figure AI robot project. However, the A-share market is policy-driven, so its future trajectory remains uncertain.
