Warriors Two, Sword twin

[p.i.klein]

On Warriors two http://www.hkmdb.com/db/movies/view.mhtml?id=5945&display_set=eng
you have credited Meng Hoi and Chin Yuet Sang as the Sword Twins. I agree with Meng Hoi, but not with Chin Yuet Sang. I think Chin Yuet Sang is taller and has a quite different nose then the other Sword Twin.
Anybody an idea who the second sword twin is?
