The second Tang Yiu-kwong appears as an actor in "Techno Warriors" and "Digital Warriors", both movies on which the first Tang Yiu-kwong was AC. In addition, both of them are called 'King Tang' in the credits of the English version of "Techno Warriors". They seem to be the same person.

If nobody stops me in 15 days I will merge them.
