Sun still shining, despite sporadic setbacks

Sun Yang had been labeled China's "bad boy" of swimming for a number of out-of-pool scandals, but the young star says he has learned a lot from the ups and downs and is ready to embark on a new phase of his career.

Sun, who shot to fame after winning gold medals in the 400m and 1,500m freestyle events at the 2012 London Olympics, has been involved in a series of scandals over the past year or so.

In early 2013, he was suspended from engaging in commercial activities after quarreling with long-time coach Zhu Zhigen, who disapproved of his romance with an air stewardess and criticized his breaking of team rules.
