Same name, same chinese credits, same period of activity... I wonder if they're the same person.
1. Ling Hon (2) 凌漢 (2)
2. Ling Hon (1) 凌漢 (1)

They are not the same person. Ling Hon (2) is not in the movies listed at Ling Hon (1). I splitted the name a few weeks ago.
I'm working on the identification of Ling Hon (1). He could be unknown No. 2 at that cast page:

www.angelfire.com/az3/chia/castg/jod.htm

Identified Ling Hon (1).
I added 44 movies to Ling Hon (1).
His name is in the cast lists of "Behind the Storm", "Hellfire Angel", "Tea House" and "Beloved Son of God".
