Perhaps you should try some spelling variations:
shang hai » shang kai, dang hai, chang ha
qian yan » qian jun, qian yi
yang jin » yang jun, ying jin, shang jin
yang jie » yang di, yang jui, yang xi
kang han » kang chen, kong hang, zhang han
nan ya » nan yan, nana yaa
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 ((nan ya) OR (qian yan)) daun ((yang jin) OR (yang jie)) ((kang han) OR (shang hai)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang yan ((nan ya) or (qian yan)) daun ((yang jin) OR (yang jie)) ((kang han) or (shang hai)) ;~".
• Adding a wildcard symbol may retrieve word variants: wang yan ((nan ya) or (qian yan)) daun ((yang jin) OR (yang jie)) ((kang han) or (shang hai)) ;*.
