Perhaps you should try some spelling variations:
shang kai » shang hai
qian yan » qian jun, qian yi
yan wang » yuan wang, yang yang, qian wang
hua chen » jui chen, yu chen, a chen
yang jie » yang jin, yang di, yang jui
he chen » zhe chen, jie chen, ke cheng
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 ((he chen) OR (hua chen)) ((yang jie) OR (yang xi)) shang kai ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "qian yan wang ((he chen) OR (hua chen)) ((yang jie) or (yang xi)) shang kai ;~".
• Adding a wildcard symbol may retrieve word variants: qian yan wang ((he chen) OR (hua chen)) ((yang jie) or (yang xi)) shang kai ;*.
