Chinese Jiangxi Zhen Pin and other marks help appreciated.

I bought this little 3" diameter cup the other day. Looks to be made in the late Republic period. We have with help translated the first
part to be Jiangxi Zhen Pin mark and the second part to be what we think is
Jin Shan Da Yi. Depending on how it is written would help determine the meaning as in Da Yi or is it Dayi. Any help appreciated.

These probably made in very late roc or early proc. Still hand written mark reason I date late roc. They made alot of these better looking. I think was made for Restaurants
