Perhaps you should try some spelling variations:
zwang iii » zugang iii, klang iii
yang zili » yang dali, yang li
die david » de david, dawe david, time david
yan wang » yuan wang, yang yang, qian wang
yang iii » klang iii, yang di, yang jui
form die » formel die, formen die, former die
david ng » david g, david n, david a
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: yan wang ((((yang iii) OR (zwang iii))) OR (yang zili)) form die david ng hai ;~.
• Adding a wildcard symbol may retrieve word variants: yan wang ((((yang iii) or (zwang iii))) or (yang zili)) form die david ng hai ;*.
