Perhaps you should try some spelling variations:
yang guang » yang yang, yan guan, yang liang
yan liang » yang liang, wang liang, you liang
tan chwee » tan khee, tan chinhwee
tan chew » tan cheng, tan siew, tan chia
lee kyu » lee kyung, lee keun, lei kyun
long du » long d, long do, long run
kyu a » yu a, kyi a

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 liang) OR (yang guang)) ((tan chew) OR (tan chwee)) lee kyu a long du ;~.
• Adding a wildcard symbol may retrieve word variants: ((yan liang) or (yang guang)) ((tan chew) or (tan chwee)) lee kyu a long du ;*.
