Perhaps you should try some spelling variations:
yang guang » yang yang, yang liang
chen chung » chen chuling, chen shuang, chen chuan
chung ming » cheng ming, chung mona, zhang ming
ming jeong » min jeong, ming kong
jeong shu » jeong su, cong shu
yan guan » gan guan, yan yuan, yihan guan
nan yan » nan ya, wang yan, qian yan
li chen » 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 (nan yan)) li chen chung ming jeong shu ;~.
• Adding a wildcard symbol may retrieve word variants: lang ((((yan guan) or (yang guang))) or (nan yan)) li chen chung ming jeong shu ;*.
