Perhaps you should try some spelling variations:
dong ping » dong sin, dong bin, dong jung
where guo » where do, where sun, where obo
yang yang » wang yang, wang yan
ping csa » ping ceo, ping fa, ping jia
guo ming » guo jing, guo xin, guo feng
yang jui » yang judy, yang yi
2 where » 4 where
yang xi » yang yi
csa 2 » csa _, usa 2, cs 2

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "dong ping csa 2 where guo ming ((((yang yang) OR (yang xi))) OR (((yang jui) OR (yang di)))) ;~".
• Adding a wildcard symbol may retrieve word variants: dong ping csa 2 where guo ming ((((yang yang) OR (yang xi))) OR (((yang jui) OR (yang di)))) ;*.
