Perhaps you should try some spelling variations:
yang yang » wang yang, wang yan
yang mind » yang cindy, yang jin, sang minh
shang hai » shang kai, dang hai, chang ha
hong than » hong tan, long thanh, hong hai
yang fan » zhang fan, yang dean, yang jin
shi ding » shi ling, shi lin, shi rong
shi dan » shi fan, shi jian

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 fan ((shi dan) OR (shi ding)) yang mind ((shang hai) OR (hong than)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "yang yang fan ((shi dan) OR (shi ding)) yang mind ((shang hai) or (hong than)) ;~".
• Adding a wildcard symbol may retrieve word variants: yang yang fan ((shi dan) OR (shi ding)) yang mind ((shang hai) or (hong than)) ;*.
