How can I change font ?

[happywky]

I need to use Chinese font such as Google noto(https://www.google.com/get/noto/) only in the language-skills section(one of the left part), how can I do it?

In most of the case, to edit a theme you'll create a child theme https://learn.getgrav.org/themes/customization#theme-inheritance and in there you'll be able to customize anything. To change font, you'll need to add a CSS rule that applies that font to the section of the page you want.
