Help with markings on Blue white porcelain vase

by Helen

Hi, I have a vase passed to me by my grandmother who acquired it from a relative. It is a blue white porcelain vase with images of men by a bridge with a few trees.

Are the marks genuine?

I have a picture of the lid of the vase, does it appear genuine?

Many thanks for any help or advice anyone can give me.
