Perhaps you should try some spelling variations:
yang liang » wang liang, yan liang, peng liang
liang chen » liang choon, chang chen, kang chen
yang yang » wang yang, wang yan
chen weng » chen wang, chen zheng, chen rong
kong weak » long weak, kong sek
weng yi » wong yi
yi kong » yi rong, yi kyoung

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