Perhaps you should try some spelling variations:
chen chung » chen chuling, chen shuang, chen chuan
chung han » cheng han, chung chuan, chung hsuan
lang yan » wang yan, wang yang, zhang yan
yang jun » yang jui, pang jun, yang jin
yang yi » yang xi, yang jui
a chen » ta chen, _ chen, n chen
ed a » jed a, red a, eds a
kyul » kaul, kyu, yul

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: ((((lang yan) OR (yang jun))) OR (((yang di) OR (yang yi))))ng ed a chen chung han kyul a ;~.
• Adding a wildcard symbol may retrieve word variants: ((((lang yan) or (yang jun))) or (((yang di) or (yang yi))))ng ed a chen chung han kyul a ;*.
