W u Zhigang is a Chinese billionaire whose wealth is derived from his family's stake in the Wens Foodstuffs Group, one of the country's largest producers of poultry and pigs. He is a member of one of the eight founding families who established the company in 1983. The company was built on a highly successful and innovative contract farming model, where the company partners with a vast network of small family farms, providing them with chicks, piglets, feed, and veterinary support, and then buys back the mature animals for processing and sale.

This asset-light model has allowed Wens to scale up its operations at a tremendous pace to meet China's huge demand for meat. After the company went public on the Shenzhen Stock Exchange in a major IPO, the founding families, including Wu's, became billionaires from their substantial ownership stakes. He has served as a director of the company, playing a key role in its long-term strategy.
