Why do many people write "boring" and how can we write the "pen power" of calligraphy?

First, the brushwork is not correct, such as seal script and regular script, which requires the pen to start at the front, the center to carry the pen, and the end to return to the front;

Second, the posture is incorrect, the posture should be correct when writing, and the posture of eyes, body and hands should be correct;

Third, the root refers to the wrist, the wrist is the elbow, the elbow is the shoulder, the shoulder is the waist, and the waist is the foot. Down-to-earth, coherent from top to bottom, natural and powerful words!
