Perhaps you should try some spelling variations:
wuhan china » tuan china, yunnan china
yang yang » wang yang, wang yan
huei ying » hui ying, hoi ying
yan guan » gan guan, yan yuan, yang guang
wei yang » pei yang, wei yang's, wei shang
wei wang » wen wang, wei shang, wei qiang
long do » long d, long du, longer do

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