Beginning of spring solar terms should be based on weather changes, timely increase or decrease clothing. Be sure to take good care of Yang to avoid colds or other respiratory infections caused by late spring cold. The key points of health preservation in different seasons are different, and the theory of health preservation in traditional Chinese medicine holds that "spring corresponds to liver" Therefore, in spring, "nourishing the liver" should be the first priority. The key to nourishing the liver lies in good emotional conditioning. We should be open-minded, optimistic, guard against arrogance and rashness, avoid depression and keep a quiet and happy mind.

Pay attention to the physiological characteristics of the liver in diet and aftercare, soothe the liver and relieve qi, so as to make the liver qi unobstructed without affecting other viscera. Eat something sweet and divergent, not sour. Because the sour taste enters the liver, it has astringent taste, which is not conducive to the rise of yang and the release of liver qi.

Food with pungent smell can be properly selected, such as onion, ginger, garlic, coriander, peanut, leek and Toona sinensis. And eat less spicy, hot and dry food, so as not to encourage excessive internal heat. You can also eat some sweets, such as red dates, sweet potatoes and brown sugar. Appropriately, it is beneficial to tonify temper and avoid spleen injury caused by excessive liver fire. Chrysanthemum tea, green tea, jasmine tea and other teas are cool but not cold, refreshing and suitable for drinking in spring.

It is suggested that people with qi deficiency can eat more foods that strengthen the spleen and replenish qi, such as yam, rice porridge, honey, peanuts, milk, chicken and so on. People with deficiency of both qi and yin should eat more foods that benefit qi and nourish yin, such as tofu, bean sprouts, carrots, shepherd's purse, tremella, lily and duck.
