Approach ban and FAF/FAP is not the same.
Approach ban would in most ops' I've seen be outer marker or equalivent, if no such thing exists it's a 1000' agl.
Steve the P. is right about both FAP and FAF for HKG. FA(F)is for (F)ix as in a ground based determined fix point, I think usually on a non precision approach like the LOC only in HK. FA(P) is only on (P)recision approaches and normally where the nominel glide path intercepts with the "platform" final approach altitude.
Good luck
