4- Tongzi ? cups, plate and teapot

[Rec]

Bottom is unmarked. I'm hoping these are from Tonghzi period and not Guangxu. On the bottom of the small plate there is some sort of stamp (pic nr 5) , which says it's from Tonghzi period.
I'm very curious on your expert opinion

These look mid-20th Century or later to me

Guangxu to early republic, common ware, but with a bit crude decoration.

Thank you Peter
I guess i need to do some more homework  :)
Is it the painting style or the shape of the bottom which make this a guagxu to early republic piece?
