Perhaps you should try some spelling variations:
shang kai » shang hai
wang tan » wang yan, wang ban, wang dan
yang hua » wang hua, ying hua, wang hui
yang hui » wang hui, yang muxi, zhang hui
yang jui » yang judy, yang di, yang yi
yang xi » yang di, yang yi
hong 7 » hong w, hong a, hong g

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 tan ((yang hua) OR (yang hui)) tan ((yang jui) OR (yang xi)) ((shang kai) OR (hong 7)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang tan ((yang hua) or (yang hui)) tan ((yang jui) OR (yang xi)) ((shang kai) or (hong 7)) ;~".
• Adding a wildcard symbol may retrieve word variants: wang tan ((yang hua) or (yang hui)) tan ((yang jui) OR (yang xi)) ((shang kai) or (hong 7)) ;*.
