Wang Xiaochuan was hired the day he graduated at Tsinghua University by Sohu.com to create a new search engine. With a small team of 12 students from nearby Tsinghua University, Wang lead the group to develop a new search engine within 10 months. The Sogou search engine (Sogou.com) was launched on 3 August 2004 and operated as a separate division within Sohu. In 2006, Sogou invented Sogou Pinyin, the eventual dominant input platform used in China for both desktop PC and mobile. In 2007, Sogou established a search curriculum with Tsinghua University in order to stimulate the recruitment and development of future engineers to the company. Wang Xiaochuan is known as the "Goalie of the East Gate" for the relentless recruitment from Tsinghua. In 2008, Sogou launched the Sogou Browser.
