Perhaps you should try some spelling variations:
shang kai » shang hai
hong jong » hong kong
wang dan » wang yan, wang yidan, wang yang
wang ban » wang yan, wang yang, bang bang
yang hui » yang jui, wang hui, yang muxi
hui dan » hui kian, hui yang, oui dans
yang yi » yang xi, yang jui

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 dan) OR (wang ban)) yang hui dan ((yang di) OR (yang yi)) ((shang kai) OR (hong jong)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wang dan) OR (wang ban)) yang hui dan ((yang di) or (yang yi)) ((shang kai) or (hong jong)) ;~".
• Adding a wildcard symbol may retrieve word variants: ((wang dan) OR (wang ban)) yang hui dan ((yang di) or (yang yi)) ((shang kai) or (hong jong)) ;*.
