According to the "Directors Directory" of the Taiwanese directors guild is

Gam Sing-Yan

http://hkmdb.com/db/people/view.mhtml?i ... ay_set=eng

the same person as

Tien Han

http://hkmdb.com/db/people/view.mhtml?i ... ay_set=eng

and Kam Chiu-Pak

http://hkmdb.com/db/people/view.mhtml?i ... ay_set=eng

If that is true (and it must be, I trust the book) Gam Sing-Yan is listed at "Miracle of Love" with three different names!

Someone objects if I merge the three names in a few days?

Merged:
