vintage Chinese chop mark pottery hand painted sauce dishes or dipping bowls

Lot of six Chinese pottery dishes all hand painted, marked with chop marks in red on the back. These I think have a little age to them, vintage but probably not antique? They're very roughly made, heavy ceramic, not porcelain.

All are about 4 1/4" in diameter. There's two each of two of the florals, one each of two of the florals. They're clean without discoloration and don't have cracks or damage from use. I love the green and pink of these dishes, so pretty!
