W ei Ying-Chiao is a Taiwanese billionaire and one of the four Wei brothers who own and run the Ting Hsin International Group, a massive food and beverage conglomerate. He is the third of the four brothers. The family's business was started by their father in Taiwan. The brothers made their fortune by being among the first Taiwanese businessmen to invest heavily in mainland China in the early 1990s. Their most famous and successful brand is Master Kong, which they built into a dominant player in the Chinese market for instant noodles and ready-to-drink teas.

The massive success of the Master Kong brand in China is the primary source of the Wei family's multi-billion dollar fortune. In addition to their core food and beverage business, the family has other interests, including ownership of the Dicos fast-food chain in China and a stake in the Taipei 101 skyscraper. Wei Ying-Chiao has been particularly involved in the family's real estate and other ventures. However, the family's business has also been at the center of a major food safety scandal in Taiwan, which led to a widespread consumer boycott and legal troubles for some family members.
