Perhaps you should try some spelling variations:
yang guang » yang yang, yan guan, yang liang
than china » tuan china, han china, wuhan china
yang wang » yang yang, yan wang, yang liang
pei yang » wei yang, hui yang, pei yun
yang le » yang li, yang jie, wang lei
long du » long do, long run, long did
long d » long do, long _, long 2

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 wang) OR (yang guang)) ((than china) OR (wang hua)) pei yang le ((long du) OR (long d)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((yang wang) or (yang guang)) ((than china) or (wang hua)) pei yang le ((long du) OR (long d)) ;~".
• Adding a wildcard symbol may retrieve word variants: ((yang wang) or (yang guang)) ((than china) or (wang hua)) pei yang le ((long du) OR (long d)) ;*.
