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

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