You can lean forward slightly, stand upright, and bend slightly when you stand and write in calligraphy. Hold the paper on the desktop with the palm of your left hand, and keep your right hand almost straight. The posture of writing will also change with your standing, palms down and hands almost flush with your arms. Stand with your feet apart, and the distance between your feet is roughly equal to your shoulder width. Wrist and arm movements are used to complete writing; If you write particularly large words, you even need to use the movement of your waist to write, and your feet can be separated to make the writing action bigger. Writing methods should also be changed accordingly. Because extra-large words need a vat of pens, they are not light after being dipped in ink. If you still hold the pen with your five fingers, I'm afraid you will be overwhelmed. You should make the tiger's mouth close to the pen, grasp the round root of the pen with five fingers, and write with the joints of wrist, elbow, arm and waist in coordination.
