Perhaps you should try some spelling variations:
wuhan china » tuan china, yunnan china
yang shang » fang sheng, yang yang, yan zhang
gain yang » dan yang, daun yang, yin yang
shang kai » shang hai
tan yang » dan yang, tan ying, tan yong
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.

• If you are trying to use Boolean operators, they must be ALL CAPS: wang yan ((tan hua) OR (wuhan china)) ((gain yang) OR (tan yang)) yang shang kai ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang yan ((tan hua) or (wuhan china)) ((gain yang) OR (tan yang)) yang shang kai ;~".
• Adding a wildcard symbol may retrieve word variants: wang yan ((tan hua) or (wuhan china)) ((gain yang) OR (tan yang)) yang shang kai ;*.
