Perhaps you should try some spelling variations:
wuhan china » tuan china, yunnan china
yang shang » fang sheng, yan zhang, yang guang
gain yang » dan yang, daun yang, tan yang
yang yang » wang yang, wang yan
shang kai » shang hai
lang yan » wang yan, wang yang, zhang yan
tan hua » tuan hua, wang hua, tan chia

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: lang yan ((tan hua) OR (wuhan china)) gain yang yang shang kai ;~.
• Adding a wildcard symbol may retrieve word variants: lang yan ((tan hua) or (wuhan china)) gain yang yang shang kai ;*.
