There is a photo of Ma Sha uploaded on Liu Jin-Zhen's page - http://hkmdb.com/db/people/view.mhtml?i ... ay_set=eng

At first I thought, that it's a mistake, but then a googled for Liu Jin-Zhen's Chinese name and the search found books with Ma Sha's pics.

So, maybe Ma Sha and Liu Jin-Zhen is the same person, or maybe not.

An investigation needed

According to Worldcat, Ma Sha is an alias of Liu Jin-Zhen.
