For lumbar disc herniation, we should always maintain a correct sitting posture: the upper body is straight, the abdomen is in, the jaw is miniature, and the lower limbs are close together. If possible, the knee joint should be slightly higher than the hip. When sitting in a chair with a backrest, try to keep your back close to the back of the chair to reduce the fatigue of lumbosacral muscles.

They are unique skills and should be handed down by ancestors! Very impressive.
