Tomb-Sweeping Day, also known as outing festival, outing festival and ancestor worship festival, is both a natural solar term and a traditional festival. The climate in the Qingming period is characterized by rainy and humid weather, and it is warm and cold at first sight. Therefore, the diet should be light, so that the body function that has just "woken up" can be slowly restored and adjusted to a vigorous state. In the choice of food, we must pay attention to its seasonality, which is beneficial to our health.
