I strongly suspect these two editors are one person:

http://www.hkmdb.com/db/people/view.mht ... ay_set=eng

My only evidence is that What Price Survival has Jun Yue in the DB, but is listed as Chun Yue in the English credits though, but I bet I'm right :p

I would expect these Chung Shing Yuens to be one person too:

http://www.hkmdb.com/db/people/view.mht ... ay_set=eng

I also think Jun Yue is Chun Yu.

Both worked for the same company, Newport.

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