Perhaps you should try some spelling variations:
wang wang » wang yang, wang liang, wang yan
wang yong » wang yang, wang hyoung, wang yan
yi cheng » yu cheng, xi cheng, yi chang
chan eng » chan fong, chan kang, chan ming
chan jan » chain jane, chan alan, chan kang
yi chen » jui chen
chun h » chung h, chun _, chun i

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 wang) OR (wang yong)) yang ((yi chen) OR (yi cheng)) ((chan eng) OR (chan jan)) chun h ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wang wang) OR (wang yong)) yang ((yi chen) or (yi cheng)) ((chan eng) or (chan jan)) chun h ;~".
• Adding a wildcard symbol may retrieve word variants: ((wang wang) OR (wang yong)) yang ((yi chen) or (yi cheng)) ((chan eng) or (chan jan)) chun h ;*.
