Perhaps you should try some spelling variations:
yang guang » yang yang, yan guan, yang liang
quan guan » gan guan, quan guo, yan guan
chen chih » chen chiu, chen zhi, chou chih
chih sing » chih p'ing, chih hang, chih yung
sing kong » king kong, hong kong
jui chen » yi chen
kong siu » kong eiu, wong siu, dong sin
nan yan » nan ya, wang yan, qian yan

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 ((((nan yan) OR (yang guang))) OR (quan guan)) jui chen chih sing kong siu ;~.
• Adding a wildcard symbol may retrieve word variants: lang ((((nan yan) or (yang guang))) or (quan guan)) jui chen chih sing kong siu ;*.
