Perhaps you should try some spelling variations:
yang guang » yan guan, yang liang
than china » tuan china, han china, wuhan china
yang yang » wang yang
tan chia » tuan china, can china, dan china
wen lang » wen wang
long do » long d, long du, longer do
lang a » lang 3, lang _, erlang 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: ((yang yang) OR (((yang guang) OR (wang yan)))) ((tan chia) OR (than china)) wen lang a long do ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((yang yang) or (((yang guang) or (wang yan)))) ((tan chia) OR (than china)) wen lang a long do ;~".
• Adding a wildcard symbol may retrieve word variants: ((yang yang) or (((yang guang) or (wang yan)))) ((tan chia) OR (than china)) wen lang a long do ;*.
