CET-4 translation has nothing to do with playing Cuju, right?

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 cold food from damaging the body, everyone comes to take part in some sports activities to exercise. Therefore, this festival is a distinctive festival, with both sad tears and laughter.
