I found this in home I moved in to. I can not find any info on it. The mark seems to be stamped, no cracks, always indoors. Please email me, it wont let me upload a picture. The mark is not in English and it does not say anything about where it was made. Just has Chinese marking on bottom.
You have to attach pictures.
See the image below, that is where you select the image(s) on your computer.

Sorry it took me a bit to get the file small enough.
Not sure about the left two characters in the seal mark, but the character style is one used in the second half of the 20th century. The decoration also looks as if it was from about that period. Perhaps a few decades. If the mark is on an unglazed bottom, it is likely on the later side.
Yes the marks are on unglazed bottom. Thank you!
