Perhaps you should try some spelling variations:
wuhan china » tuan china, yunnan china
gain yang » dan yang, daun yang, tan yang
han chang » huang chang, than change, can change
chang hai » chang ha, shang hai, change has
yang han » yang fan, kang han, yang dean
tan hua » tuan hua, wang hua, tan chia
wang » wing, wan, lang

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "wang yan ((tan hua) OR (wuhan china)) gain yang han chang hai ;~".
• Adding a wildcard symbol may retrieve word variants: wang yan ((tan hua) OR (wuhan china)) gain yang han chang hai ;*.
