He is frail, haggard and often spotted in a wheelchair.
Despite battling leukaemia, veteran Taiwanese singer Gao Ling Feng is adamant that he will not stop performing or touring, as it is "the only thing that makes me happy".
The 63-year-old father of five told local reporters at Hard Rock Hotel on Thursday: "I don't want to lie in bed all day, I'll feel very miserable."
He was in town to perform at the Taiwan's Four Heavenly Kings 2013 Concert tomorrow. The gig also features fellow Taiwanese singers Ye Qi-Tian, Zhang Di and Shen Wen-Cheng.
Prior to his visit here, Gao had told Taiwanese reporters that the show in Singapore will definitely go on "unless I die before that".
Best known for his flamboyant image, outlandish stage outfits and Ah Beng dance moves in the 70s, he now looks like a shadow of his former self.
But make no mistake - the iconic pop star, nicknamed Frog Prince by his fans, is a fighter.
Gao, whose groovy hits Big Eyes, Burst of Fire in Winter and Girl's Dimples made him a household name in the Mandopop scene alongside the likes of late singers Fong Fei-Fei and Teresa Teng, was diagnosed with cancer last November.
In the past year, his prognosis had been gloomy - he has had three failed chemotherapy sessions and his weight plummeted from 76kg to his current 57kg. Due to his body's self-defence mechanisms breaking down, he catches all kinds of infections easily.
