Perhaps you should try some spelling variations:
kyoung weak » kong weak
yang yang » wang yang, wang yan
yang kang » yang guang, yang liang, wang yang
kang chen » chang chen, jane chen, kang han
chen weng » chen wang, chen zheng, chen rong
yi kyoung » kim kyoung
weng yi » wong yi

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: ((wing OR wan) OR lang) yang yang kang chen weng yi kyoung weak ;~.
• Adding a wildcard symbol may retrieve word variants: ((wing or wan) or lang) yang yang kang chen weng yi kyoung weak ;*.
