Latex 更改字体大小 - Awesome Source CV

Question

I'm using this Latex template for my resume and I'd like to shrink the font size of the body text to fit more information but I'm not sure how to do so.

I'm not familiar with using Latex packages and I didn't see a font size number I could easily change; does anyone know what I can try? Here is some truncated code for the formatting class.

You can go a bit smaller if you replace \LoadClass[a4paper]{article} with

\LoadClass[a4paper,9pt]{article}

in your class. Or even tinier:

\LoadClass[a4paper,8pt]{extarticle}
