Perhaps you should try some spelling variations:
zhang wei » zhen wei
wei qiang » wei shang
qiang yan » qian yan, wang yan, zhang yan
wing yan » wang yan, wing ian, wing tan
yang jin » yang jun, ying jin, shang jin
yang jie » yang jui, yang xi, yang jun
yang yi » yang xi, yang jui
zhen » zheng, when, chen

You may be able to get more results by adjusting your search query.
