Mingen attended the Methodist-founded Soochow University, where she passed well, but ran into problems in that the university's paperwork said that she was a man.
She adopted the professional name of Li Jing, and after working as a singer, a model and actress in a soap opera, she became an infomercials moderator. She became a star on Eastern Media Group's Shopping Channel 東森購物.
In 2002 she married a man 14 years her junior.
In her 2004 autobiography Li Jing wrote that she had been born a hermaphrodite, and had had surgical correction.
In 2009 Dr Zhang Qizhong wrote an article in a Taiwanese medical journal to share his experiences in 35 years as a doctor. He wrote about how in 1981 he had arranged a sex change for a 23XY male, and at the end of the article revealed that he was talking about Li Jing. This was picked up by the regular press. He was criticized for revealing the name of a patient, but defended himself in that Li Jing had discussed her operation in her autobiography.
Li Jing was featured in the 2012 movie Drug War 毒戰 which was filmed in China.
