Perhaps you should try some spelling variations:
shang hai » dang hai, chang ha, hong hai
qian yan » qian jun, qian yi
yan wang » yuan wang, yang yang, qian wang
wang wei » zhang wei, wang zhi
wei chen » wei shen, frei chen, jui chen
ying jin » yang jin, jing ji, yang jie
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 wei chen ((ying jin) OR (yang xi)) ((shang hai) OR (shang kai)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "qian yan wang wei chen ((ying jin) or (yang xi)) ((shang hai) OR (shang kai)) ;~".
• Adding a wildcard symbol may retrieve word variants: qian yan wang wei chen ((ying jin) or (yang xi)) ((shang hai) OR (shang kai)) ;*.
