Perhaps you should try some spelling variations:
yang wang » yang yang, yan wang, yang guang
yuan wang » yan wang, yuan kang, yuan chang
chang min » zhang ming, chan ming, chang ann
chang mae » chang ha, changes made
jeong su » jeong _, jeong mi, jeong 情
hua yeo » chua yee
hong yu » wong yue

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 wang) OR (yuan wang)) hua yeo ((chang min) OR (chang mae)) ((jeong su) OR (hong yu)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang ((yang wang) or (yuan wang)) hua yeo ((chang min) OR (chang mae)) ((jeong su) or (hong yu)) ;~".
• Adding a wildcard symbol may retrieve word variants: wang ((yang wang) or (yuan wang)) hua yeo ((chang min) OR (chang mae)) ((jeong su) or (hong yu)) ;*.
