Perhaps you should try some spelling variations:
yang guang » yang yang, yang liang
ming jeong » min jeong, ming kong
chen chan » chen chuan, cheung chan, chen chung
chan ming » kian ming, chan eng, chan fong
jeong shu » jeong su, cong shu
yan guan » gan guan, yan yuan, yihan guan
jui chen » yi chen
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 ((((yan guan) OR (yang guang))) OR (nan yan)) jui chen chan ming jeong shu ;~.
• Adding a wildcard symbol may retrieve word variants: lang ((((yan guan) or (yang guang))) or (nan yan)) jui chen chan ming jeong shu ;*.
