Tomb-Sweeping Day is a traditional festival in China, and it is also the most important festival to worship ancestors and sweep graves. Grave-sweeping is commonly known as going to the grave and offering sacrifices to the dead. Most Han people and some ethnic minorities visit graves in Tomb-Sweeping Day. According to the old custom, when sweeping graves, people should bring food, wine, fruit, paper money and other items to the cemetery, offer food to the graves of their loved ones, then burn the paper money, cultivate new soil for the graves, break some green branches and insert them in front of the graves, then kowtow and worship, and finally go home after eating and drinking.
