I merged your submissions. First some observation. I don't know why these are called urns, but they were definitely not made to contain ashes. Anyway, this is a common form of vessel (let's say vase) made in the past.
I wonder if you could upload an enlarged image of the last uploaded picture (top one in this merged submission) so that details of the faces are visible?
The color makes me doubt it is Chinese. It seems rather to be Japanese, despite the Chinese mark.
