How to draw figures, movements and virtual and real lines in martial arts books in the 1980s and 1990s? Do you have any software? Please tell us!

Brother, you'll know the answer if you think about it.

Envy our "ancients". Their dexterous hands can draw such wonderful line drawings, and they are easy to understand.

The pictures in the 1980s and 1990s are basically printed, but the pictures of mothers and parents are still hand-painted.

Brothers, martial arts lovers, come on, you can draw with meticulous brushwork.

My grandfather is a level 8 mechanic. The mechanical drawings he drew are really beautiful.

I saw a scientist draw a Leo on TV. Lions are the same as real ones.

So we should pursue perfection in the future.
