Perhaps you should try some spelling variations:
qian wang » yiqian wang, qian rong, qian yan
shang hai » shang kai, dang hai, chang ha
yan wang » yuan wang, yang yang, yan liang
yang jui » yang judy, yang di, yang yi
yang jin » yang jie, yang jun, ying jin
yu chen » yu cheng, yi chen, yulu chen
yang xi » yang di, yang yi
yan yu » yun yu, yan yuan, yang yue

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: ((yan wang) OR (qian wang)) yan yu chen ((((yang jui) OR (yang jin))) OR (yang xi)) shang hai ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((yan wang) OR (qian wang)) yan yu chen ((((yang jui) or (yang jin))) or (yang xi)) shang hai ;~".
• Adding a wildcard symbol may retrieve word variants: ((yan wang) OR (qian wang)) yan yu chen ((((yang jui) or (yang jin))) or (yang xi)) shang hai ;*.
