Why is it called "crayon" Xiao Xin?

Because Japan is a "silver-like wax spear", it is "wax"

Because it is a painting, it has something to do with a pen, which is called "pen"

However, I am not satisfied with the status quo of small land, I always want to innovate, and I can only cultivate a little land, so this is Xiao Xin.

Therefore, it is called the crayon "Xiao Xin"
