The teacher asked everyone to hand in an 8-inch calligraphy painting or other categories. I don't know anything. What should I do? Do something simple?

That's easy ~ You said that you can't do anything, in fact, anyone can draw, but the difference is the difference between exquisite and rough painting ~ I guess you can't calm down and carefully copy a painting with complex lines, so find a painting with simple composition and composed of several large areas of color blocks. This is to type the manuscript with a pencil first, then draw with a needle pen (if not, use an ordinary signature pen instead), and then use crayons/colored lead/watercolors and so on.
