Perhaps you should try some spelling variations:
yang guang » yang yang, yan guan, yang liang
quan guan » gan guan, quan guo, yan guan
chou chih » chen chih
yan yuan » yan guan, fang yuan, nan yan
jui chou » jui chen, jui che, lu chou
p'ing » p'wing, p'ping, p'ming
dong » doing, long, done
sin » sign, sind, skin

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 yuan) OR (yang guang))) OR (quan guan)) jui chou chih p'ing dong sin ;~.
• Adding a wildcard symbol may retrieve word variants: lang ((((yan yuan) or (yang guang))) or (quan guan)) jui chou chih p'ing dong sin ;*.
