Perhaps you should try some spelling variations:
yang guang » yan guan, yang liang
yang yang » wang yang
thanh vu » thanh van, thanh _
wei yang » pei yang, wei wang, wei yang's
yang kim » yong kim, kang kim, hyung kim
kim jang » kim jane, kim jong, kim kwang
jang hui » wang hui, yang hui, zhang hui
wang » wing, wan, lang

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 yan) OR (yang yang))) OR (yang guang)) ((ya hua) OR (thanh vu)) wei yang kim jang hui ;~.
• Adding a wildcard symbol may retrieve word variants: ((((wang yan) or (yang yang))) or (yang guang)) ((ya hua) or (thanh vu)) wei yang kim jang hui ;*.
