Historical legend: As for the name of winter melon, it is said that Shennong loved the people like a son and cultivated "square melons", namely, east melons, pumpkins, watermelons and north melons.

And ordered them to go their separate ways and settle in their closed places for the benefit of the people.

As a result, the south, west and north melons all went to the sealed place, and only the east melon did not obey the distribution, saying that the East China Sea was windy and life was not used to it.

Shennong had to let it change places. There was too much wind and sand in the west, the north was afraid of cold, the south was afraid of heat, and finally went to the east.
