Perhaps you should try some spelling variations:
yang guang » yang yang, yan guan, yang liang
than china » tuan china, han china, wuhan china
you liang » you xian, you liangzhi
china lei » china led, china less, china law
lei kyun » lee kyung, lee kyu, pei yun
long ago » long arm
kyun xi » kyun pin
long d » long do, long du, long _
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 (you liang))) OR (yang guang)) than china lei kyun xi ((long ago) OR (long d)) ;~.
• Adding a wildcard symbol may retrieve word variants: ((((wang yan) or (you liang))) or (yang guang)) than china lei kyun xi ((long ago) or (long d)) ;*.
