Perhaps you should try some spelling variations:
wang daoping » wang xiaoping, wang danning, wang xiaobing
tuan hua » tuan vu, yuan hui
yang tin » yang jin, yang lin, yang jing
tin dang » tin hong, bin dann, ein dank
tan hua » wang hua, tan chia, tan puay
yu yang » du yang, yi yang, yu fang
hai » hadi, haji, hari

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 yanling) OR (wang daoping)) ((tuan hua) OR (tan hua)) yu yang tin dang hai ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wang yanling) or (wang daoping)) ((tuan hua) OR (tan hua)) yu yang tin dang hai ;~".
• Adding a wildcard symbol may retrieve word variants: ((wang yanling) or (wang daoping)) ((tuan hua) OR (tan hua)) yu yang tin dang hai ;*.
