How long has the history of eating melon seeds on Dragon Boat Festival been?

The history of eating palm seed on Dragon Boat Festival is 1900 years.

The earliest food of the Dragon Boat Festival should belong to the "owl soup" of the Western Han Dynasty. Quoting Historical Records and Biography of Emperor Wudi, he said: "The Han Dynasty sent owls to Dong Jun, and on May 5th, officials were given owl soup. Eat it because of the evil bird. " Probably because owls are difficult to catch, the custom of eating owl soup didn't last. Filing is the protagonist of the Dragon Boat Festival-Zongzi, which appeared after the Eastern Han Dynasty. It was not until the Jin Dynasty that zongzi became the festival food of the Dragon Boat Festival. "Local customs": "May 5, the summer of the same solstice, ... first celebrate these two festivals, then wrap them with glutinous rice leaves, mix them with millet, and cook them with pure ash juice. At the same time, there is a kind of Dragon Boat Festival food called "turtle", which was only a flash in the pan in the Jin Dynasty and then disappeared. Only Zongzi, called "Zongzi" in Local Conditions and Customs, has become the most popular Dragon Boat Festival food in Qu Yuan's legend for thousands of years.

According to the practice recorded in "Local Customs", the zongzi at that time was mainly millet, and no other fillings were added except millet. However, under the ingenious management of China people who pay attention to diet, the zongzi we see today has changed in shape and content.
