Tian won gold in the 10 m platform event in the 2000 Sydney Olympics. In the Summer Olympics 2004, he won the bronze medal in the 10 m platform event and a gold medal in the synchronised platform event.
Since then, he and another gold medal winner, the Chinese female diver Guo Jingjing, often appeared together in public activities. They were better known together as Liang Jingjing (亮晶晶, Tian and Guo's combined given names, synonymous with the word for 'sparkling').
After winning his multiple Olympic medals, Tian received numerous invitations to lend his name and face to corporate promotions. His involvement in commercial activities, and perhaps other disputes with the national team, have led the national team to fire him after repeated warnings. In spite of this, Tian continued to practice diving with a provincial team. He maintained his diving standard and won a medal at the following National Games of China. Although there was great public interest in him rejoining the national team, it did not happen. Tian has since then split his schedule between diving training and public activities. Finally on March 25, 2007, Tian announced his retirement as a diver.
On July 29, 2008, it was announced that Tian would not be rejoining the national team and participating in the 2008 Beijing Olympics.
