Perhaps you should try some spelling variations:
than china » tuan china, han china, wuhan china
yang guang » yang yang, yan guan, yang liang
yan liang » yang liang, wang liang, you liang
tan china » tuan china, can china, dan china
longer a » longer _
yang 3 » yang _, gang 3, lang 3
yang 8 » yang _

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 china) OR (than china)) won ((yang 3) OR (yang 8)) longer a ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((yan liang) or (yang guang)) ((tan china) OR (than china)) won ((yang 3) or (yang 8)) longer a ;~".
• Adding a wildcard symbol may retrieve word variants: ((yan liang) or (yang guang)) ((tan china) OR (than china)) won ((yang 3) or (yang 8)) longer a ;*.
