Perhaps you should try some spelling variations:
wuhan china » tuan china, yunnan china
wang kang » wang yang, wang liang, wang yan
han china » hang china, than china, can china
yang yang » wang yang, wang yan
yang lin » yang jin, wang lin, yang li
lin dann » bin dann, sein dann, ein dank
dann hai » dang hai, dann hat, dann kam

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: ((wang kang) OR (wang yanling)) ((wuhan china) OR (han china)) yang yang lin dann hai ;~.
• Adding a wildcard symbol may retrieve word variants: ((wang kang) or (wang yanling)) ((wuhan china) or (han china)) yang yang lin dann hai ;*.
