Anyone recognize this vintage Chinese vase?

Hello, all. I received this Chinese-made vase as a wedding present more than 25 years ago. It has some heft to it, and it is a foot tall. The floral design seems to be lightly impressed or incised, and it is found on both sides. The vase is a light blue and as seen underneath it is made in China. I got a close up photo of the makers mark.

It was purchased new from a Southern California department store.

Does anyone know where in China it was made of, or its approximate value? I continue to enjoy using it for cut flowers, so it's not sitting on a shelf collecting dust.

Thank you, all.

 

Only a decorative value so what anybody would give for it .
