Perhaps you should try some spelling variations:
wang yong » wang hyoung, wang shiyong
chai wang » chen wang
wang yang » wang liang, wang yanling
shang hai » shang kai, dang hai, chang ha
kim chai » ka chai
yang jin » yang jie, yang jun, ying jin
hong hai » zhong tai, dang hai, hong tan

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 yong) OR (wang yan)) kim chai wang yang jin ((hong hai) OR (shang hai)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wang yong) OR (wang yan)) kim chai wang yang jin ((hong hai) or (shang hai)) ;~".
• Adding a wildcard symbol may retrieve word variants: ((wang yong) OR (wang yan)) kim chai wang yang jin ((hong hai) or (shang hai)) ;*.
