Perhaps you should try some spelling variations:
kang chen » chang chen, jane chen, tang chun
yan yang » yang yang, yao yang, dan yang
yang yun » tang yun, yang yue, yang yang
yang jun » yang jui, pang jun, yang jin
yong wah » long way, yong cai, yoon wah
kang han » kong hang, zhang han, dang hai
yun tan » yun jang
wang » wing, wan, lang

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: wang yan yang yun tan ((yang jun) OR (yong wah)) ((kang han) OR (kang chen)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang yan yang yun tan ((yang jun) or (yong wah)) ((kang han) OR (kang chen)) ;~".
• Adding a wildcard symbol may retrieve word variants: wang yan yang yun tan ((yang jun) or (yong wah)) ((kang han) OR (kang chen)) ;*.
