Perhaps you should try some spelling variations:
wuhan china » tuan china, yunnan china
gain yang » dan yang, daun yang, tan yang
yao shang » gao shang, yao yang, hao zhang
shang hai » shang kai, dang hai, chang ha
lang yan » wang yan, wang yang, zhang yan
tuan hua » tan hua, tuan vu
yuan hui » yuan fei, jaan hui, yang hui
yang yao » yang yang, wang yan, yang yi

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 ((((tuan hua) OR (yuan hui))) OR (wuhan china)) gain yang yao shang hai ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "lang yan ((((tuan hua) OR (yuan hui))) or (wuhan china)) gain yang yao shang hai ;~".
• Adding a wildcard symbol may retrieve word variants: lang yan ((((tuan hua) OR (yuan hui))) or (wuhan china)) gain yang yao shang hai ;*.
