I don't think I'll be much of a help.
As for Zhang Sanfeng, he will be played by Yu Cheng Hui.
Liu Jing doesn't look that bad from the event. I can't believe I'm saying this, but she actually looks better than Ady. Probably because of Ady's bad costume. Ady's costume looks something similiar to Alyssa's one outfit, except for it's purple (sorry I couldn't find any better pics).
