Perhaps you should try some spelling variations:
chuan jeng » chua beng, chuan bang
yang guang » yang yang, yang liang
jeng dong » eng hong, zeng doug
dong sign » dong sin, among sign, dong bin
yan guan » gan guan, yan yuan, yihan guan
fan guon » gan guan
yi chen » jui chen

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 guan) OR (yang guang))) OR (fan guon)) yi chen chuan jeng dong sign ;~.
• Adding a wildcard symbol may retrieve word variants: lang ((((yan guan) or (yang guang))) or (fan guon)) yi chen chuan jeng dong sign ;*.
