"How many have 'blown up' as you say, again? ;)."
I can name more than three, that's for sure.
As for the names you mention, personally, I don't think there is enough evidence to say they aren't frauds. YONG would obviously be closest, then TRIT. But it's hardly 100%.
I know you're very bullish on CCCL, but I don't share your sentiment. They come from Fujian (not a good place to be from lol), they sell stock at P/E 3, then they do it again, despite having very strong cash flow. To me, that's a no no.
