How did Ching-Ying Lam die? Tell me the real cause of Ching-Ying Lam's death.

Ching-Ying Lam died of liver cancer in 1997 at the age of 45. ?

One month before his death, Ching-Ying Lam knew that he would die soon. Not only did he not allow his family to reveal his illness to the outside world, but he even took the initiative to break up with his girlfriend King-Tan Yuen. One week before his death, he refused to visit his daughter and other disciples, and he didn't want everyone to see his lingering illness. Compared with his humorous image on the screen, the loneliness in real life is even more touching ~
