Liu Changqing wrote in the poem "Surprise": Flowers and willows on the stranger will compete in spring, and carp and carp in the pool will have early shade. Suddenly I heard a thunderbolt from heaven, and the animals and insects dried up. It vividly describes the awakening season, the gradual warming of spring and the infestation of snakes and insects.
In the scary season, not only peach blossoms began to bloom all over the hillside, but also orioles began to sing, and many insects lurking underground began to stir: after sleeping for a winter, the weather was finally warm, and I was going out to feed and reproduce!
Therefore, on this day, many families will get up early, smoke in every corner of the house with Ai Xiang in their hands, and drive away snakes, insects, mosquitoes, mice and so on with the scent of Ai Xiang.
