Perhaps you should try some spelling variations:
huang ting » huang jing, huang ying, huang bin
wang plan » wang yan, wang ban, wang dan
plan what » mean what
can earn » can learn
gong min » jong min, song min, gong meng
can wan » can win, can wage, can when
hong yu » wong yue

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 plan what ((can wan) OR (can earn)) huang ting ((hong yu) OR (gong min)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang plan what ((can wan) OR (can earn)) huang ting ((hong yu) or (gong min)) ;~".
• Adding a wildcard symbol may retrieve word variants: wang plan what ((can wan) OR (can earn)) huang ting ((hong yu) or (gong min)) ;*.
