The difference between the written 2 and Z lies in the shape and direction.

2 Complete in one stroke, and the writing order is first left vertical and then right horizontal. It should be noted that the strokes are horizontal to the right, horizontal to the left, and vertical is too prominent.

Z is completed in two strokes, and the writing order is to write the left semicircle first and then the vertical line. The left semicircle occupies the middle square, and the strokes that need attention are vertical, and the vertical strokes should be written straight.
