Taipei - A JJ Lin lookalike has angered the Singaporean singer's fans by posing as him in nightclubs in China and raking in about NT$7 million (S$290,000) in two years, said Taiwan Apple Daily today.

According to a profile on Chinese website NetEase, Fan Yixian of Taiwan made his debut as a singer in China in 2012 and has been called "the mainland's JJ Lin" because he has a small dimple like Lin's.

Apple Daily said Fan began as a JJ Lin impersonator, but later passed himself off as Lin blatantly, borrowing his hairstyle, talking like him and singing JJ Lin hits such as Jiangnan and Cao Cao.

Fan has been billed as "Taiwan's prince of love songs JJ", for example, in posters for his performances, said the report. Fan is due to perform at a bar in Hunan tonight, at a show advertised as "I have a date with JJ", said the daily.

Warner Music, which manages Lin, said its staff in Beijing would collect evidence and try to take legal action if necessary.

Fan, in an appearance on Anhui TV last year, said he had been a DJ and a taxi driver, reported Apple Daily. He described impersonating Lin as a phase, and said he hoped to sing his own songs in his own style one day. The daily spoke to a man who said he was Fan's agent. The man said he had seen Fan's Taiwan identity document, adding that Fan earns about 8,000 yuan (S$1,600) for every show.
