(1) sitting posture
The correct posture of sitting on a book can be summarized in eight words: straight head, straight body, open arms and steady feet.
1. The key to opening the arm is that the two arms open naturally, and the included angle between the big arm and the small arm exceeds 90, so that the four joints of finger, wrist, elbow and shoulder can cooperate easily and harmoniously, and the strength of the body can be smoothly transmitted to the pen tip;
2. To meet the above requirements, you should try to sit up straight. The distance between the chest and the edge of the table is about 3 inches (adjust the distance according to the size of the handwriting). Don't cling to the desktop or hunch over;
3. Keep your head straight, keep your head straight and lean forward slightly. Do not skew, ensure that the viewing angle is moderate, and the distance between the eyes and the paper is roughly maintained at 30-40 cm. Hold down the paper on the left hand side and adjust the position of the paper so that the words being written are always in the best range of eyes and hands.
4. Put your feet flat naturally, and bend your legs flat. When your feet are parallel or slightly forward, your legs should not cross (commonly known as Erlang legs).
(2) Standing posture
The posture of the book is to hang your wrist flexibly, and at the same time, because of the condescending and wide perspective, it is easy to observe the overall situation and master the rules. The specific requirements of the book-standing posture are: the feet are slightly separated, and one foot leans forward slightly to keep the body balanced.
The upper body is slightly tilted, the waist is slightly arched, and the distance should not be too far. The left hand presses the paper and the right hand hangs the wrist to write. It is worth noting that the desktop should not be too low to avoid excessive bending and fatigue.
(3) Writing methods
The ancients attached great importance to the method of writing, saying that "whoever learns calligraphy should learn to write first." There are many ways to write in ancient times, such as twisting the tube, holding the tube, pulling the stirrup, three fingers and five fingers. There are also different views on the tightness of writing. Wang Xizhi argues that it is important to write, and only by writing tightly can you concentrate on using a pen. Su Dongpo advocates being open-minded, that is, holding the pen loosely and making it easy to turn the pen.
In fact, "tightness" and "looseness" are two contradictory aspects that are both opposite and unified. Writing is for good strokes, so "tight" means that the pen tip can be well controlled to prevent it from drifting and sliding, while "loose" means that the pen in the hand is flexible and the pen tip can be changed at will, so that the word has a lasting appeal. The scientific method of writing can be summarized as: the pen is vertical, the fingers are empty, and it is natural to relax.
