A Question About Zelkova

[cemteco]

Hi there,

A friend of mine have bought this for me as a gift.
Could anyone tell me exactly what type of bonsai is she?
On a piece of paper attached to her, it says "Zelkova" but on a video I saw that Zelkovas have bigger leaves.
Also I am wondering about her age.
Thanks in advance.

This is a Chinese Elm, Ulmus parviflora.

Age would only be an estimate, but for that, we would need to see a photo that shows the trunk.
