The number 1: Don't write straight, it's oblique, but not too oblique. Don't understand it as a connection between two diagonal corners, but the pen is not closed in the upper right corner until the lower left corner.

Number 2: It looks like a duckling sitting on the ground, but pay attention to it, with a round head and a flat body. The horizontal strokes of the pen should be written from the lower left corner to the lower right corner, one stroke at a time, without stopping.

The earliest tools used by human beings to count are fingers and toes, but they can only represent numbers within 20. When the number was large, primitive people mostly counted pebbles and beans. Gradually, people were not satisfied with counting by grains, so they invented the method of knotting to describe counting, and described counting on hides, bones, trees and stones.
