[1] Sun Yue signed his first professional contract with Chinese Basketball Association side Beijing Olympians in 2002 at the age of 17.

[5] After recovering from his illness, Sun finally made his debut on 7 December 2008 against the Milwaukee Bucks, scoring four points in five minutes of play.

[9] Sun then suffered a left ankle sprain during practice with the D-Fenders and missed the remaining D-League games.

Since he was a member of the team when the Lakers ultimately won their championship, he did receive a ring and was crowned as an NBA champion.

[12][13] Sun joined the New York Knicks, but was waived on 7 October 2009, before the next season started, due to a stress fracture in his knee.

This was seen as a chance for the Chinese national team to gain further experience against international competition in preparation for the 2008 Summer Olympics, which Sun would also compete in.

Sun earned a silver medal in the 2009 FIBA Asia Championship after China finished as runners-up in the tournament.

[16][17][18] According to Chinese media Baidu Sports, Sun presented his NBA championship ring to his girlfriend Chen Lu when he proposed.
