Someone added the last few days many Taiwan low budget movies to the database, some with Dick Wei. Very interesting. I wonder if that movies are available on VCD/DVD.
The name Law Yui is listed as the director of three of that movies. Could that be Alexander Lo Rei? Same chinese characters and at one movie Law Cheung On is the action director (Law worked a lot with Alexander Lo and is also a possible alias for him).

I am who added almost all those rare taiwanese movies' credits (and very soon I will add a hundred more, mainly by Tomas Tang and Joseph Lai), and also created "Law Yui" because I was not sure if he was Alexander Lo Rei although their symbols are the same.

If you are sure they are the same person, you have my permission to merge them.

I do not have those VCDs, it was my compatriot dlopez who sent me those credits screenshots to my gmail. Maybe he can tell you where can you find them. You can contact with him via PM.

If nobody objects I merge Law Yui with Alexander Lo in a few days. I think it must be the same person.
