2. Han Festival, a traditional festival in China, is also called "October Dynasty", "Ancestor Festival" and "Ghost Festival" on the first day of the tenth lunar month every year. People call it Ghost Head Festival, which is a traditional festival of sacrifice in China. It is said that it originated in the Zhou Dynasty. The Cold Clothes Festival is popular in the north, and many northerners will offer sacrifices on this day to commemorate their deceased relatives. This is called sending cold clothes. In the north, Hanyi Festival, Tomb-Sweeping Day in spring and Mid-Autumn Festival on July 15 are collectively called the three "ghost festivals" in China. At the same time, this day also marks the arrival of severe winter, so it is also a day to send warm clothes to parents, lovers and others who care about it.
