Perhaps you should try some spelling variations:
yang yang » wang yang, wang yan
tuan hua » tuan vu, yuan hui
tan chia » tuan china, than china, can china
yang min » yang mind, tang min, yang lin
yang jin » yang jie, yang jun, ying jin
hong hai » shang hai, zhong tai, dang hai
tan hua » wang hua, tan puay

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 ((tuan hua) OR (((tan hua) OR (tan chia)))) tan ((yang min) OR (yang jin)) hong hai ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "yang yang ((tuan hua) or (((tan hua) or (tan chia)))) tan ((yang min) OR (yang jin)) hong hai ;~".
• Adding a wildcard symbol may retrieve word variants: yang yang ((tuan hua) or (((tan hua) or (tan chia)))) tan ((yang min) OR (yang jin)) hong hai ;*.
