He split with partner Wang Feng after they won a gold medal in the 3m synchronised springboard event at the 2005 World Championships.

The two staged a reunion and won gold at the same event in the 2006 Diving World Cup in Changshu, China.

At the 2008 Olympics He Chong defeated an elite field of divers including, the two time world champion Alexandre Despatie, the 2006 world cup champion Qin Kai, and eight time Olympic medalist Dmitri Sautin.

He is hoping to be the first diver to regain an individual diving Olympic title at the 2016 Rio Games, after a rare off day led to a loss of his title in 2012 where he won only bronze, his only loss in a Fina World Cup final, World Championships, or Olympics he competed in from 2008 to 2014.

He was left off the Chinese team for the 2016 Rio Games in favor of his own brother He Chao, the 2015 World 3 metre Champion.
