Tomb-Sweeping Day has a long history of sweeping graves to worship ancestors, which has become a habit. Sweeping the grave is also called sweeping the grave, offering sacrifices and going to the grave. Tomb-Sweeping Day visited the grave because he was in shock, the vernal equinox had passed, the snow and ice melted and the plants sprouted. People think about the graves of ancestors, whether foxes and rabbits have pierced holes, and whether they will collapse because of the rainy season. So on the one hand, they went to the grave to remove weeds, trim branches and add some shovel to the grave; On the other hand, prepare some sacrifices, burn some paper money, hang some notes on the branches and hold a simple ceremony to show the memory of the deceased. On this day in ancient times, people got together to make friends, help the old and take care of the young, and went to the suburbs for a good spring outing. Before and after Tomb-Sweeping Day, there were many traditional colorful cultural and sports activities, such as tug-of-war, swinging, flying kites, playing polo and fighting cocks.
