Perhaps you should try some spelling variations:
yang guang » yan guan, yang liang
yang yang » wang yang, wang yan
guang hua » wang hua, gang hu, guang eu
ren weng » den weg
weng tin » weng yi
hong hai » shang hai, zhong tai, dang hai
hua ren » hua chen
hong g » hong ng, hong w, hong 7

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: yang yang guang hua ren weng tin ((hong g) OR (hong hai)) ;~.
• Adding a wildcard symbol may retrieve word variants: yang yang guang hua ren weng tin ((hong g) or (hong hai)) ;*.
