Perhaps you should try some spelling variations:
yang guang » yang yang, yan guan, yang liang
tuan china » wuhan china, can china, taiwan china
you liang » you xian, you liangzhi
tan chwee » tan khee, tan chinhwee
pei yun » lei kyun, mei yung, pei yang
long do » long d, long du, longer do
yun a » run a, un a, yun _

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: ((you liang) OR (yang guang)) ((tuan china) OR (tan chwee)) pei yun a long do ;~.
• Adding a wildcard symbol may retrieve word variants: ((you liang) or (yang guang)) ((tuan china) or (tan chwee)) pei yun a long do ;*.
