With 29 years of experience in China's dairy industry, Weijian Wang is an experienced entrepreneur known for his fresh ideas in dairy making and business management. He constantly sets new industry standards by creating innovative products and building smart operations.

In 1997, Mr. Wang founded Handan Coiner Food, introducing China's first "fresh milk home delivery" service with milk boxes. To make even better products, he began building a world-class factory in 2017. By June 2020, this modern, 500-million-RMB facility was up and running. Soon after, in September 2020, he launched the premium Greek yogurt brand Öarmilk in Beijing.

Under his leadership, Öarmilk stood out in a tough market by focusing on high quality, great value, and simple, clean ingredients. Between 2021 and 2025, Öarmilk's sales grew more than 100 times, jumping from millions to nearly 1 billion RMB. This made it China's top premium Greek yogurt brand. Because of his strict focus on production standards, Öarmilk earned the top BRC A+ global food safety certification. It also successfully entered Hong Kong's high-end supermarkets, proving that a Chinese dairy brand can win on the global stage.
