Perhaps you should try some spelling variations:
dong ryang » dong yang, dong hoang
yang hui » yang jui, yang muxi, zhang hui
wang hui » wang hua, wang zhi, wang wei
ping yi » ming yi, ping yu, jiang yi
a weit » a west, a soweit
a wei » ha wei, ma wei, a web
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)) ye ((a wei) OR (a weit)) ((yang hui) OR (wang hui)) ping yi ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((dong ryang) or (wang yan)) ye ((a wei) OR (a weit)) ((yang hui) or (wang hui)) ping yi ;~".
• Adding a wildcard symbol may retrieve word variants: ((dong ryang) or (wang yan)) ye ((a wei) OR (a weit)) ((yang hui) or (wang hui)) ping yi ;*.
