Four s √: totally enclosed structure, flat sector, equidistant vertical pen.
The outer "mouth" shape is flat and wide, with the upper width and the lower width being narrow, and the whole is slightly shoulder-resistant. Bevel the left vertical pen, then write down the right, gradually becoming lighter, pay attention to the length, and collect the pen lightly; Pick up the pen horizontally, lightly in the horizontal direction, slightly thin in the middle and slightly arched. When in place, slightly lift the nib to the lower right, slightly thicker, and then stroke it down to the left, with an inclination angle greater than the left vertical, and gradually become lighter, slightly higher than the left vertical. (After internal writing, you should back cover the cross. )
The internal word "er" can be written as a dot and an ellipsis here, and attention should be paid to the position (the center of gravity is equidistant from the word "mouth"), which echoes each other. Click the pen to take the pen, and the right oblique angle is consistent with the left vertical; Pen skimming is a semi-virtual pen picking. Write the pen to the lower right first, and then leave it to the lower left. The angle is slightly larger than the inclination of the right vertical.
Finally, the bottom cross is slightly thicker, actually picking up the pen, slightly resisting the shoulder tilt, and holding the pen in the correct vertical position.
"Si" is a very important dividing unit in ancient China, which is echoed by heaven and earth: the sky has four seasons, the earth has four sides, and people have four bodies. The division of time and space makes "Si" have a complete connotation. "All four corners are ready" describes things as perfect, "safe and sound" and "four pavilions and eight places" describes things as stable and safe.
