Perhaps you should try some spelling variations:
yang zili » yang dali, yang li
wan wang » wen wang, yan wang, wang yang
yang iii » klang iii, zwang iii, yang di
david ng » david g, david n, david a
i david » 2 david, die david, iii david
form i » form _, form a, reform i
ng hai » dang hai, hong hai

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: wan wang ((yang iii) OR (yang zili)) form i david ng hai ;~.
• Adding a wildcard symbol may retrieve word variants: wan wang ((yang iii) or (yang zili)) form i david ng hai ;*.
