Perhaps you should try some spelling variations:
yunnan china » urban china, tuan china, yunnan sheng
wuhan china » tuan china
wang liang » wang yang
wang ning » wang jing, wang yang, wang yong
ban yang » dan yang, tan yang, wang yang
yang lin » yang jin, wang lin, yang li
lin lone » lin ling, lin zong
star » start

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 ning) OR (wang liang)) ((wuhan china) OR (yunnan china)) ban yang lin lone (star OR stay) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wang ning) or (wang liang)) ((wuhan china) OR (yunnan china)) ban yang lin lone (star or stay) ;~".
• Adding a wildcard symbol may retrieve word variants: ((wang ning) or (wang liang)) ((wuhan china) OR (yunnan china)) ban yang lin lone (star or stay) ;*.
