Others:
There are two Yip Ching listed but they are not the Yip Jing I have in mind. However, one of the Yip Ching which consist of 3 characters has its last character missing. Perhap, it shd be listed as "Yip Ching ?" temporary. I tried and failed to cut & paste chinese character from the DB. I will look elsewhere and update Yip Jing later.

I added the names to the cast list.
