Perhaps you should try some spelling variations:
peng pong » ping pong, eng hong, peng yeng
jeng dong » eng hong
zeng doug » zeng douglas
hua chen » jui chen, yu chen, a chen
wong yue » wang yue, hong yu
yi chen » jui chen
ping ku » ping ke, ping yu
ku wong » kie wong

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 ((peng pong) OR (((jeng dong) OR (zeng doug)))) ((hua chen) OR (yi chen)) ping ku wong yue ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang ((peng pong) or (((jeng dong) OR (zeng doug)))) ((hua chen) or (yi chen)) ping ku wong yue ;~".
• Adding a wildcard symbol may retrieve word variants: wang ((peng pong) or (((jeng dong) OR (zeng doug)))) ((hua chen) or (yi chen)) ping ku wong yue ;*.
