Perhaps you should try some spelling variations:
shang hai » shang kai, dang hai, chang ha
yana hua » wang hua, tan hua, ya hua
yang min » yang mind, yang jin, tang min
yang lin » yang jin, wang lin, yang li
hong hai » zhong tai, dang hai, hong tan
hua ren » hua chen
wang » wing, wan, lang

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 yana hua ren ((yang min) OR (yang lin)) ((hong hai) OR (shang hai)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang yanling yana hua ren ((yang min) or (yang lin)) ((hong hai) OR (shang hai)) ;~".
• Adding a wildcard symbol may retrieve word variants: wang yanling yana hua ren ((yang min) or (yang lin)) ((hong hai) OR (shang hai)) ;*.
