To practice Tai Ji Chuan, we must "relax" and "keep the airway open". The lung governs the qi of the whole body, and the qi of the lung regulates the qi of the whole body. Therefore, when practicing, you should make the gas unobstructed, and the airway should not be stagnant. Therefore, in practicing boxing, don't hold your breath, but always relax and calm down. When practicing boxing, you should cooperate with breathing, opening and closing. As a result of the above requirements, people who practice Tai Ji Chuan can relax their mind and adjust their breathing during boxing, and feel comfortable and energetic every time they practice boxing. The body perspires slightly, which increases the metabolism in the body, thus relieving mental stress and playing a fitness role.
