Perhaps you should try some spelling variations:
chen wang » chen yang, chen rong
chen ping » chen rong, chen yang
yang jui » yang judy, yang di, yang yi
fan xing » fan ying, fan xibo, von xing
yang xi » yang di, yang yi
tan xin » tan sinh, tan ying
tong a » kong a, hong a, jong a

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

• If you are trying to use Boolean operators, they must be ALL CAPS: ((chen wang) OR (chen ping)) ((yang xi) OR (yang jui)) cheng ((tan xin) OR (fan xing)) tong a ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((chen wang) or (chen ping)) ((yang xi) or (yang jui)) cheng ((tan xin) OR (fan xing)) tong a ;~".
• Adding a wildcard symbol may retrieve word variants: ((chen wang) or (chen ping)) ((yang xi) or (yang jui)) cheng ((tan xin) OR (fan xing)) tong a ;*.
