Dear Members, judging from porcelain itself and decoration, this vase is from Republic medium period, I think.
The calligraphy and mark probably can help for a more precise dating.
Thank you for your attention.
Unfortunately the first character of the name on the mark is not legible as it is. But, judging by mark type age signs of glaze and black writing, this is likely early republic in my view.
I have a better picture of the mark, but anyway the right period has been identified.
Thank you Peter.
