Before Wang Zhidong enrolled in university in Beijing, he had never touched a computer. While at college, he taught himself how to write software, and began developing programs for the rising number of computer firms in the area. Upon graduation in 1989, he founded his own company, Chinese Star. It created software enabling Western applications to run on Chinese-language PCs.

The introduction of Windows as a major player in the PC market motivated Zhidong to leave Chinese Star and develop a new program, one that could translate Windows for Chinese machines. He was joined by Yan Yanchou, a technology expert famed for designing China’s first computer systems and creating Chinese Character DOS. They launched Suntendy Electronic Technology and Research.

The new firm created RichWin, which enabled Chinese-language conversion for Windows. The pair sought financing and obtained an investment from the Stone Group, an electronics distributor. They then renamed the firm Beijing Stone Rich Sight Information Technology Company (SRS). RichWin was released publicly in 1993, and by the mid-1990s, it was used by 80% of China’s three million PCs.

While on a trip to the U.S. in 1995, Zhidong encountered the Internet for the first time. It inspired him to begin planning SRS’s online strategy, and when he returned home he started “Project Surf“, an effort to write webpages. By 1997 RichWin had forums, chat rooms, news, and multimedia content. SRS’s portal became China’s most-used site, generating over three million hits daily.

Zhidong dreamed of expanding the site’s usage to the significant Chinese population in other locations. He contacted Sinanet, another Chinese-language site founded in the U.S. with a presence in Taiwan. The two firms merged to combine their strengths, forming Sina. In 1999, Sina went public with a listing on the NASDAQ and extended its reach to Hong Kong and North America.
