In addition, we should master some graphic drawing software, such as Photoshop and CorelDRAW. I believe bookstores and school libraries also have piles of such books.

This is the basis of graphic drawing. As a graphic advertising designer, you naturally do some packaging design and poster design. (Graphic design such as advertising posters here requires certain typesetting skills. There are books about advertising typesetting in the library. You can borrow them first.

There are books on color matching, but I suggest you don't read them yet, because you may not understand them. This requires real artistic color skills. But many girls have a good sense of color, which is uncertain. Experience is more important.

When you see the cover design of other people's books in your daily life, you can pay more attention to it and prepare for your own drawing!

You can read the font design, graphic composition, color composition, layout design, poster design and packaging design mentioned above, but you are not an art major, so these books look very laborious and time-consuming. I suggest you learn more about (layout design) and the graphic drawing software (Photoshop, coreldraw) I mentioned above. This is a practical thing, others can be used according to experience. It will take a long time.

There are many (Photoshop, coreldraw) tutorials on the Internet, you can have a look!

I hope it helps you!
