Perhaps you should try some spelling variations:
yang liang » wang liang, yang yang, peng liang
yan liang » wang liang, you liang, yan wang
dan chen » don chen, sudan chen, dan china
yang jie » yang jin, yang jui, yang yi
wong sam » wong sau, wong lai, kong sar
yang xi » 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 liang) OR (yang liang)) dan chen ((((yang xi) OR (yang di))) OR (yang jie)) wong sam ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang ((yan liang) OR (yang liang)) dan chen ((((yang xi) or (yang di))) or (yang jie)) wong sam ;~".
• Adding a wildcard symbol may retrieve word variants: wang ((yan liang) OR (yang liang)) dan chen ((((yang xi) or (yang di))) or (yang jie)) wong sam ;*.
