The emergence of the Mid-Autumn Festival can be traced back to the worship of ancestors in ancient times and related festivals. It is a traditional cultural festival to remember ancestors, and its cultural core is to respect ancestors and do filial piety. In July and a half, people still worship land and crops. Scatter the offerings into the fields. After burning paper, it is wrapped around the ears of crops with five-color paper cut into pieces. Legend has it that hail can be avoided and a bumper harvest can be achieved in autumn. Many places in the country will choose to eat ducks in July and a half. Because ducks swim in the water, they take the meaning of praying for the river lights.
