Chinese Export? Very interesting and unusual

Any help on this beautiful, unusual dish would be greatly appreciated. It is beautifully hand painted and has a different scene on all five sides. Seems to be a courting story. The painted eyes seem asian but the female caracters have blonde hair and the same woman's head seperated all of the scenes, coming off the 5 feet of the dish. The first panel has the man approaching the woman with a green cloth. next she is wearing the cloth and he is offering some type of gold dish, next offering another gold perhaps drinking dish, 4th they are together offering the gold dish to the tree, last they are together intimately. The tree changes position from being inbetween them, to being on the right during thier offering, and last on the left when they are together. Some kind of marraige dish? Fertility?
Approx 9"wide, 10" top of fish to bottom. Has proper wear and crackling and not a fake. No markings I can find.
Thanks very much.
