Perhaps you should try some spelling variations:
shang hai » shang kai, dang hai, chang ha
qian yan » qian jun, qian yi
yan wang » yuan wang, yang yang, qian wang
yang jie » yang jin, yang di, yang jui
di chen » yi chen, jui chen, don chen
li chen » yi chen, jui chen
yang xi » yang di, yang yi, yang jui

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