Perhaps you should try some spelling variations:
dong ryang » dong yang, dong hoang
pei yang » wei yang, hui yang, pei yun
yang hui » yang jui, wang hui, yang muxi
hui ping » hui ying, chui ling, hui sin
ping shu » cong shu, ping ku, ping yu
a pei » a peri, a bei, a pen
ye a » yet a, e a, me a

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 ryang) OR (wang (yan OR ryan))) ye a pei yang hui ping shu ;~".
• Adding a wildcard symbol may retrieve word variants: ((dong ryang) OR (wang (yan OR ryan))) ye a pei yang hui ping shu ;*.
