Perhaps you should try some spelling variations:
yang guang » yang yang, yan guan, yang liang
tang yang » wang yang, yang yang, tan yang
yang ming » yang jing, yang mind, yang keming
ming dong » ming kong, jeng dong, ming hung
wing ian » wing tan, twinn ian, wing sun
nan yan » nan ya, wang yan, qian yan
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: ((wing ian) OR (dong di)) ((yang guang) OR (nan yan)) tang yang ming dong sin ;~.
• Adding a wildcard symbol may retrieve word variants: ((wing ian) or (dong di)) ((yang guang) or (nan yan)) tang yang ming dong sin ;*.
