Perhaps you should try some spelling variations:
clan kang » chan kang, yuan kang
kang chen » chang chen, jane chen, kang han
yan clan » das clan, yan guan, yan yuan
yang jin » yang jie, yang jun, ying jin
wong sam » wong sau, wong lai, kong sar
yang xi » yang jui
yang yi » yang jui
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 clan kang chen ((((((yang xi) OR (yang yi))) OR (yang di))) OR (yang jin)) wong sam ;~.
• Adding a wildcard symbol may retrieve word variants: wang yan clan kang chen ((((((yang xi) or (yang yi))) or (yang di))) or (yang jin)) wong sam ;*.
