Nourishing Qi mainly starts from two aspects, one is to maintain the vitality, and the other is to regulate the Qi machine. If the vitality is sufficient, then life is full of vitality, and the qi mechanism is unobstructed, then the body is healthy.
1. To maintain good qi, the first step is to follow the four seasons and be cautious in daily life. If the human body can adapt to the changes of the four seasons, it can protect the yang qi and prevent damage. As stated in the "Su Wen · Qi Tong Tian Lun": "If the qi in the sky is clear and calm, then the will and intention will govern, and if it is followed, the yang qi will be solid. Although there are thieves and evil, it cannot harm. This is due to the order of time.". Therefore, the four seasons of health preservation and daily life care are mainly focused on maintaining vitality.
2. To maintain good qi, it is important to cultivate and nourish the acquired body and strengthen the innate body. Dietary nutrition should be used to nourish the acquired spleen and stomach, making the essence of water and grains slightly abundant for nourishing qi. And abstinence, strengthening essence, and avoiding labor injuries are methods and measures to protect innate vitality.
