The number 4 is written with two strokes. First of all, the first stroke starts from the upper edge of the Japanese font, with the midpoint slightly to the right, draws a straight line to the lower left, crosses the horizontal center line and touches the left boundary line, then draws a horizontal line to the right, touches the vertical center line and closes the pen; The second pen is on the upper side of the vertical center line, draw a straight line to the lower left, and touch the midpoint of the lower sideline to the left to close the pen. This is how the standard 4-character Tian Zige is written!

In principle, the Tian Zige writing of numbers is usually standardized on the left, because it is written in a math book. When writing numbers, pay attention to the position of starting and closing the pen, as well as the position of touching the edge. Only by paying attention to these details can you write naturally!
