Well he is alive and posting so I would assume no. No one who ever crosses Bolo lives to tell the story.
.....It's a long story ....
I know Bolo_Yeung very well since eary 1990s ,and he had invited me to guest-pose at his contests in Hong Kong 1990s.
And his son is David Yeung ,a bodybuilder too:
1997 Los Angeles Championships - NPC, MiddleWeight, 1st
2001 USA Championships - NPC, Light-HeavyWeight, 6th
2003 Los Angeles Championships - NPC, Light-HeavyWeight, 3rd
USA Championships - NPC, Light-HeavyWeight, 8th
And I think that he live in US now .
