Need help about mobile loading speed

Hi there,
My website has only been up for more than a week, I have just learned that the Google PageSpeed and Google Mobile-Friendly tools report that my website has a bad mobile loading speed (about 80 points on PC but only about 10 points on phone and completely unfriendly mobile - probably due to loading speed).
I’m working with my hosting provider, but I still want to ask if can I do something simultaneously to improve, such as plugins, image compression or the like?
I would really appreciate it if someone could access https://hocvienaothuat.vn and suggest me some solutions.

Hi,

Site’s performance is not the scope of theme’s support as there are many things to do with it. I can only recommend this article, that has comprehensive guide you can follow.

I hope that helps.
