What does it mean to eat duck eggs in the long summer?

Eating duck eggs in long summer refers to the custom of eating duck eggs on the same day in long summer

The custom of "eating eggs in the long summer" has a long history. As the saying goes, "if you eat eggs in the long summer, it will not be summer when it is hot." According to legend, since the day of long summer, the weather has been sunny and warm, and it has gradually become hot. Many people, especially children, will feel tired, lose their appetite and gradually lose weight. This is the so-called "squat". Nu Wa Niangniang told the people that every year during the Long Summer Festival, children hang cooked chicken, duck and goose eggs on their chests to escape the heat. Therefore, the custom of eating eggs in the long summer festival has continued to this day.

Long summer is the seventh solar term among the twenty-four solar terms and the first solar term in summer. The festival is held on May 5-7 of the Gregorian calendar every year. At this time, the bucket handle of the Big Dipper points to the southeast, and the longitude of the sun reaches 45. Long summer is an important solar term, marking the peak season for the growth of all things.
