Perhaps you should try some spelling variations:
yang yang » wang yan
wang yang » wang yan, wang liang
tuan hua » tan hua, tuan vu, yuan hui
tan yang » dan yang, tan ying, tan yong
wong sau » wong sam, wong siu, wong shiu
kong siu » kong eiu, wong siu, dong sin
hua tan » hua ban, huan t'an

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 yang) OR (wang yanling)) tuan hua tan yang yang ((wong sau) OR (kong siu)) ;~.
• Adding a wildcard symbol may retrieve word variants: ((wang yang) or (wang yanling)) tuan hua tan yang yang ((wong sau) or (kong siu)) ;*.
