The deceased Wong Ka Kui is unlikely to appear on the stage of I am a Singer, but Huang Guanzhong, who is also a member of BEYOND, has appeared on the first season of I am a Singer, singing the classic Hai Guo Tian Tian (海阔天空)>, a classic of specialized BEYOND, and a cover of Jacky Cheung's Kiss Farewell as well. But in the first season of the masters, Huang Guanzhong quickly eliminated, it is a pity.
Fortunately, in the face of this small loss, Huang Guanzhong's performance is also very calm: "Back in Hong Kong, his wife and friends will certainly come over to comfort me, but I have to tell them not to worry, this road I have been walking for 30 years, what setbacks have not tried."
