Perhaps you should try some spelling variations:
yang guang » yang yang, yan guan, yang liang
yan clan » das clan, yan guan, yan yuan
zhang ya » zhang yan, zhang y, zhang yi
yan kun » yan guan, yan yuan
ya song » a song, jae song, kyu song
zhen » zheng, when, chen
shin » skin, sein, thin

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 kun) OR (yan clan))) OR (yang guang)) zi zhen zhang ya song shin ;~.
• Adding a wildcard symbol may retrieve word variants: lang ((((yan kun) or (yan clan))) or (yang guang)) zi zhen zhang ya song shin ;*.
