Perhaps you should try some spelling variations:
dong ryang » dong yang
dong hoang » hong hong
yang's hui » yang hui
hui ying » huei ying, hoi ying, hui ping
ying shu » ying zhu, cong shu, ying hua
ma wei » mr wei
ha wei » hua wei, han wei, zhan wei
ryang » rryang
yan » ryan
yang's » ryang's

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 (dong hoang))) OR (wang yan)) yet ((ma wei) OR (ha wei)) yang's hui ying shu ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((dong ryang) or (dong hoang))) or (wang yan)) yet ((ma wei) OR (ha wei)) yang's hui ying shu ;~".
• Adding a wildcard symbol may retrieve word variants: ((((dong ryang) or (dong hoang))) or (wang yan)) yet ((ma wei) OR (ha wei)) yang's hui ying shu ;*.
