Perhaps you should try some spelling variations:
dong ryang » dong yang, dong hoang
wei yang » pei yang, wei wang, wei yang's
yang hui » yang jui, wang hui, yang muxi
hui ying » huei ying, hoi ying, hui ping
ying shu » ying zhu, cong shu, ying hua
yet a » et a, yet _, get a
a wei » a weit, ha wei, ma wei
ryang » rryang
yan » ryan
yang » ryang

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 ryang) OR (wang yan)) yet a wei yang hui ying shu ;~.
• Adding a wildcard symbol may retrieve word variants: ((dong ryang) or (wang yan)) yet a wei yang hui ying shu ;*.
