Perhaps you should try some spelling variations:
wuhan china » tuan china, yunnan china
yang guang » yan guan, yang liang
yang yang » wang yan
wang yang » wang yan, wang liang, wang yanling
pei yang » wei yang, hui yang, pei yun
hui ying » huei ying, hoi ying, hui ping
long d » long do, long du, long _

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