Perhaps you should try some spelling variations:
chen chung » chen chuling, chen shuang, chen chuan
chung han » cheng han, chung chuan, chung hsuan
yang jie » yang jin, yang jui, yang xi
yang yi » yang xi, yang jui
ong ye » ong yew, wong yue, wong yee
a chen » ta chen, _ chen, n chen
scl a » scl _, sol a, sci a
ye a » yet a, e a, me a
wang » wing, wan, lang

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: ((((wang yan) OR (yang jie))) OR (((yang di) OR (yang yi))))ong ye a chen chung han scl a ;~.
• Adding a wildcard symbol may retrieve word variants: ((((wang yan) or (yang jie))) or (((yang di) or (yang yi))))ong ye a chen chung han scl a ;*.
