Perhaps you should try some spelling variations:
yang yang » wang yang, wang yan
yang hua » yang hui, ying hua, yang jui
rene can » line can, rene ten
lee tong » lee jeong, lee kiong, lee sang
tong hui » wang hui
yang yi » yang di, yang xi, yang jui
can lee » can let, can leave, can lead

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: ((yang yang) OR (yang yi)) ((yang hua) OR (wang hua)) rene can lee tong hui ;~.
• Adding a wildcard symbol may retrieve word variants: ((yang yang) or (yang yi)) ((yang hua) or (wang hua)) rene can lee tong hui ;*.
