Perhaps you should try some spelling variations:
yunnan china » urban china, tuan china, wuhan china
gao shang » gao zhong, hao zhang
shang hai » shang kai, dang hai, chang ha
tuan hua » tan hua, tuan vu, yuan hui
tan yang » dan yang, tan ying, tan yong
yang gao » yang yao, yang fan, xing gao
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 ((tuan hua) OR (yunnan china)) tan yang gao shang hai ;~".
• Adding a wildcard symbol may retrieve word variants: wang yan ((tuan hua) OR (yunnan china)) tan yang gao shang hai ;*.
