Both solar terms have the traditional custom of eating jiaozi, but during the winter solstice, more people will eat jiaozi. When I was in beginning of winter, I ate jiaozi, because beginning of winter was at the turn of autumn and winter, so I called it "the time of communication". Jiaozi is homophonic with intercourse. Eating jiaozi nutrition on this day is a good sign.

Eating jiaozi on the solstice in winter is quite popular in the north, and there is a popular saying in the northeast that "jiaozi bowls are improper on the solstice in winter, and nobody cares about frozen ears".

Jiaozi feast:

Jiaozi has been used for banquets since 1000 years ago in the Tang Dynasty. Chang 'an, the capital at that time, was the economic and cultural center of the Tang Dynasty. In times of peace and prosperity, people's requirements for life are getting higher and higher, and food culture has also developed. In the Tang Dynasty, there was a high-class banquet in Chang 'an, called "Shao Weiyan", which was a sumptuous banquet dedicated to the emperor after the official position of the court minister was promoted.

In a menu of "Roast Tail Banquet" discovered in the Tang Dynasty and preserved to this day, this menu is equivalent to today's menu. In this menu, we found a dish called "Twenty-four Gas Wonton". Jiaozi is packaged into different shapes and contents according to the 24 solar terms. Therefore, it can be considered that today's dumpling feast may have taken shape in the Tang Dynasty.
