Perhaps you should try some spelling variations:
yang guang » yang yang, yan guan, yang liang
chen chih » chen chiu, chen zhi, chou chih
chih sing » chih p'ing, chih hang, chih yung
sing dong » sing kong, jeng dong, shin dong
yan yuan » yan guan, fang yuan, yan clan
gan guan » yan guan, quan guan, fan guon
jui chen » yi chen
nan yan » nan ya, wang yan, qian yan
sing » signg, sindg, sking
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 (nan yan))) OR (yang guang))) OR (gan guan)) jui chen chih sing dong sin ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "lang ((((((yan yuan) OR (nan yan))) or (yang guang))) or (gan guan)) jui chen chih sing dong sin ;~".
• Adding a wildcard symbol may retrieve word variants: lang ((((((yan yuan) OR (nan yan))) or (yang guang))) or (gan guan)) jui chen chih sing dong sin ;*.
