Set Of Four Tongzhi Dishes - Period Or Later?

Thanks in advance!

Looks like a recent production imitating a late Qing decoration, and Tongzhi mark, but the colors are recent, in my view.
If you are looking for antiques of the late Qing dynasty, try to avoid those with olive green color. These are frequently from a later time.
