Perhaps you should try some spelling variations:
zhang ming » zhang xin
ying yang » yang yang, yin yang, ying chang
chang min » chang mae, chan ming, chang ann
dong yang » dong hoang, wang yang, yang yang
wong siu » wong shiu, kong siu, wong sau
von sam » von sa, von sap, von scham
li li » li lin, li l, li lu

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 ((ying yang) OR (dong yang)) li li ((chang min) OR (zhang ming)) ((wong siu) OR (von sam)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang ((ying yang) or (dong yang)) li li ((chang min) OR (zhang ming)) ((wong siu) or (von sam)) ;~".
• Adding a wildcard symbol may retrieve word variants: wang ((ying yang) or (dong yang)) li li ((chang min) OR (zhang ming)) ((wong siu) or (von sam)) ;*.
