Perhaps you should try some spelling variations:
shang hai » shang kai, dang hai, chang ha
zhong zhi » zhang zhi, hong ghi, zhong tai
wang lin » wang li, wang qin, wang limin
yang lin » yang jin, yang li, yang liang
yan wang » yuan wang, yang yang, qian wang
nan yan » nan ya, wang yan, qian yan
yang yi » yang di, yang jui
yang xi » yang di, 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: ((wang lin) OR (yang lin)) nan yan wang ((yang yi) OR (yang xi)) ((shang hai) OR (zhong zhi)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wang lin) OR (yang lin)) nan yan wang ((yang yi) or (yang xi)) ((shang hai) or (zhong zhi)) ;~".
• Adding a wildcard symbol may retrieve word variants: ((wang lin) OR (yang lin)) nan yan wang ((yang yi) or (yang xi)) ((shang hai) or (zhong zhi)) ;*.
