Perhaps you should try some spelling variations:
yang yang » wang yang, wang yan
wang yong » wang yang, wang hyoung, wang yan
tan yang » dan yang, tan ying, tan yong
long tan » hong tan, long han, long thanh
tan hua » tuan hua, wang hua, tan chia
hua tan » hua ban, huan t'an
yang xi » yang di, yang yi, yang jui

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 (wang yong)) tan hua tan yang xi ((dang hai) OR (long tan)) ;~.
• Adding a wildcard symbol may retrieve word variants: ((yang yang) or (wang yong)) tan hua tan yang xi ((dang hai) or (long tan)) ;*.
