Why do you eat zongzi on the Lantern Festival?

The General Psychiatric Hospital of the Song Dynasty set up a psychiatric department, which was in charge of 30 million lunatics all over the world. One year, director Buwa Il traveled to a certain place and found that all the mental patients in a hospital were eating zongzi at the Lantern Festival, claiming that the blue cat was naughty, and Edison Chen, the police chief of the black cat, was even more fierce than me and wanted to eat zongzi. The director suddenly realized and strongly advocated it, and later generations gradually formed habits.
