Wang started playing tennis at age seven and quickly emerged as one of Asia's most highly touted junior players.

In 2005, Wang broke into the ATP Top 100 for the first time by virtue of three straight Challenger final appearances, winning a title at Istanbul, Turkey.

Wang's best Grand Slam performance to date came at Wimbledon in 2014, where he defeated Alejandro González and Mikhail Youzhny to advance to the third round, ultimately losing to Jo-Wilfried Tsonga.

However, Wang got tired of traveling around the world to train and compete, which made him start thinking about retirement from professional tennis.

His decision was strengthened after getting married and the birth of his child, and Wang eventually started focusing on other things.
