Small Chinese (?) Jar

[Bluenote]

Hello
I'm brand new and have joined hoping somebody might be able to help identify what I recently purchased. Its a small jar standing approx 9cm high with no lid and  decorated in pale blue with a white glaze over (I think). Some of the glaze appears to have been scratched off or burnt off during firing where the darker areas are on the buildings, tree branches, bridge arches, mountain tops etc. Its a very crude pot both in its throwing and decoration. There appear to be lots of age related signs such as brown crazing, rust and bubbles in the glaze. There are no marks on the bottom as such just a couple of tiny random dots of blue. Any help anyone can offer would be gratefully received, both in identifying where it came from, what it was used for, its age or meanings in the jumble of images it carries. Thanks (The post isn't allowing me to post any photos but I can post more separately if I can work it out)
