Zheng Jun has also recorded a Chinese language version of Coldplay's song "Yellow", entitled "流星" ("shooting star," pinyin: Liú Xīng), which was included in the soundtrack of the 2001 Taiwanese television series Meteor Garden I. He released another album in May 2007.
In 2007, Zheng joined the judges' panel of Happy Boys Voice, a sequel to Hunan Satellite Television's Super Girl; a controversy developed over his quarrel with fellow judge Yang Erche Namu over her ranking of a contestant from his hometown of Xi'an.
