Perhaps you should try some spelling variations:
wang yang » wang yan, wang liang, wang yanling
has done » has gone, has one, has money
gong min » jong min, song min, gong meng
yang jun » yang jui, pang jun, yang jin
one sdn » one side
yang xi » yang di, yang jui
yang yi » yang di, 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: one sdn has done when ((gong min) OR (((yang jun) OR (yang xi)))) ((wang yang) OR (yang yi)) ;~.
• Adding a wildcard symbol may retrieve word variants: one sdn has done when ((gong min) or (((yang jun) or (yang xi)))) ((wang yang) or (yang yi)) ;*.
