Perhaps you should try some spelling variations:
yong yang » yang yang, ying yang, kyoung yang
dong yang » dong hoang, wang yang, yang yang
chang min » zhang ming, chang mae, chan ming
ii chang » vii chang, yi chang, ii changes
wong sam » wong sau, von sam, wong max
di ii » dm ii
sar » sara, star, saur

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 ((yong yang) OR (dong yang)) di ii chang min ((((wong sam) OR (wong lai))) OR (kong sar)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang ((yong yang) OR (dong yang)) di ii chang min ((((wong sam) or (wong lai))) or (kong sar)) ;~".
• Adding a wildcard symbol may retrieve word variants: wang ((yong yang) OR (dong yang)) di ii chang min ((((wong sam) or (wong lai))) or (kong sar)) ;*.
