Walao, you guys are really thick. Liu Jia Chang is famous as a singer but that does not mean he is not a song-writer or director and he is not famous for writing songs for other famous singers. But he is a singer and people go to his concerts since ages ago when he started out. He was here in Singapore holding his own singing concert as recently as Sep 2014:

My uncles and aunties have his records eons ago....when he started out, he was a singer and a very famous and talented one too.
Liu Wen Zheng is a famous singer as well as an actor but he is famous with the aunties for his singing. That does not mean he did not do other things like setting up his own talent grooming company, which only closes in 1991 when he totally left the entertainment scene when he left for the USA.
It's the same as Sylvia Chang. She
is a Taiwanese actress, writer, singer, producer and director. But recently, she is famous as a filmmaker, but that does not mean she is not a famous singer for her songs. n between acting, Slyvia Chang is also a proficient singer. With many popular songs, her music has also become hits for Karaoke. In particular her song "The Cost of Love" is most commonly sung. She is also known for her song "Childhood", sung in her eponymous album Childhood.
But for some aunties and uncles not in the know, they may think Liu Chia Chang is famous for his song-writing and nothing else. Just like for those not in the know, will think Sylvia Chang is famous as a filmmaker, but she is also a famous singer and those not in the know, like the gong chee buy Narong kuniang, Liu Wen Zheng is an actor, but not only is he famous in the region as a singer, many aunties drool over him in his years in 1970's when he was younger, but many did not know that Liu Wen Zheng is also a talent groomer, like Jackie Wu, who is famous as a host and compere, but Jackie is also an entrepreneur and singer and there're people who buys his songs last time, and he is also an actor, just like Liu Jia Chang, Sylvia Chang and Liu Wen Zheng.
Only those aunties and uncles not in the know and gong chee buys like Narong cheebye, who are thick in their heads will try to pigeon-hole such enormous talented people, who are at once singer, song-writer, producer, film director and host, all rolled into one at various stages of their entertainment career.
