Perhaps you should try some spelling variations:
wuhan china » tuan china, yunnan china
yang guang » yang yang, yan guan, yang liang
yang wang » yang yang, yan wang, yang liang
pei yang » wei yang, hui yang, pei yun
long du » long d, long run, long did
long do » long d, longer do, long ago
yang d » yang di, yang du, 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: ((yang wang) OR (yang guang)) ((wuhan china) OR (wang hua)) pei yang d ((long du) OR (long do)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((yang wang) or (yang guang)) ((wuhan china) or (wang hua)) pei yang d ((long du) OR (long do)) ;~".
• Adding a wildcard symbol may retrieve word variants: ((yang wang) or (yang guang)) ((wuhan china) or (wang hua)) pei yang d ((long du) OR (long do)) ;*.
