Perhaps you should try some spelling variations:
dong ping » dong sin, dong bin, dong jung
ping day » ping fa
yang jie » yang jin, yang xi, yang yi
yang jui » yang judy, yang xi, yang yi
when su » when sun, when so
su ming » wu ming, guo ming
3 when » 4 when
day 3 » day 1

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: dong ping day 3 when su ming ((((wang yan) OR (yang jie))) OR (((yang jui) OR (yang di)))) ;~.
• Adding a wildcard symbol may retrieve word variants: dong ping day 3 when su ming ((((wang yan) or (yang jie))) or (((yang jui) or (yang di)))) ;*.
