Tomb-Sweeping Day's customs are rich and interesting. In addition to paying attention to the prohibition of fire to sweep graves, there are a series of customs and sports activities such as jogging, swinging, cuju, playing polo and inserting willows. According to legend, this is because Tomb-Sweeping Day wants to ban cold food and fire. In order to prevent the harm of cold food and cold meal to people, we all take part in some sports activities to exercise. Therefore, this festival has both sad tears to sweep the new grave and laughter for an outing. It is a distinctive festival, and it is also a very neutral festival. There is nothing unlucky. I hope I can help you.
