Chang Fu-Ning (???) and Yu Lian (??) are the same person.

Previously I identified this actor - as Chang Fu-Ning (???) - that's how he's credited in "Sex witness" and also in a Taiwanese TV-series "??":


Chang Fu-Ning has also leading roles in "Gua Fu De Nan Ren" and "Wei Qing Sha Ji", but the name ??? is not in the credits of these two movies.
Chang Fu-Ning, Chang Hsin and Chui Bo-Lun are the only actors to appear in both movies, all of them have leading roles, and the only names that appear in both movies are ??, ??? and ??.
??? is Chui Bo-Lun, ?? is Chang Hsin, that means that ?? is Chang Fu-Ning.

Chang Fu-Ning in "Gua Fu De Nan Ren":


In "Wei Qing Sha Ji (1997)":


Also! The name in Yu Lian (??) entry is wrong. You can see in credits of both movies that it's actually ??, so the romanized name should be Yu Qian.

Please change and merge.

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