Perhaps you should try some spelling variations:
gain yang » dan yang, daun yang, tan yang
yang weng » huang weng, yang yang, yang jing
weng fang » jing fang, wen wang
qian yan » qian jun, qian yi
yan yuan » yan guan, fang yuan, yan clan
fang hai » dang hai, shang hai, eang hay
wan yan » wang yan, wai yan, wang yang
nan yan » nan ya, wang yan, dan yang

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: wan yan ((yan yuan) OR (((nan yan) OR (qian yan)))) gain yang weng fang hai ;~.
• Adding a wildcard symbol may retrieve word variants: wan yan ((yan yuan) or (((nan yan) or (qian yan)))) gain yang weng fang hai ;*.
