Perhaps you should try some spelling variations:
wong laid » wong lai, kong land
yang july » yang judy, yang jun
yang jui » yang judy, yang di, yang xi
von sach » von fach, von sprach, von sa
nan yan » nan ya, wang yan, qian yan
yan jin » yang jin, yan jiu, yang jing
jin hua » jin zhuo, ming hua, ying hua
hua ren » hua chen

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: nan yan jin hua ren ((((yang jui) OR (zhang fan))) OR (yang july)) ((von sach) OR (wong laid)) ;~.
• Adding a wildcard symbol may retrieve word variants: nan yan jin hua ren ((((yang jui) or (zhang fan))) or (yang july)) ((von sach) or (wong laid)) ;*.
