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