1. A basic introduction to the beginning of winter

The beginning of winter is November 7th or 8th every year. In ancient my country, it was customary for the people to regard the beginning of winter as the beginning of winter. "Er Hou Ji Jie" said: "Li, the beginning of the establishment", and also said: "Winter, the end, the collection of all things!" Climatology divides the four seasons into standards. The average temperature in the second half of the year drops below 10℃ as winter, and "Lidong is the beginning of winter". The statement that "winter begins" is basically consistent with the climate patterns in the Huanghuai region. In the northernmost areas of Mohe and the north of Daxinganling, winter has already entered in early September! Beijing also has a winter scene in late October, and winter in the Yangtze River Basin does not really begin until around the "light snow" solar term!

2. Climatic characteristics of the beginning of winter

The beginning of winter is regarded as the beginning of winter in literature. According to climatology, the start of winter in my country has to be delayed by about 20 days. At the beginning of winter, the sun has reached 225 degrees longitude, and the northern hemisphere receives less and less radiation from the sun. However, since the heat stored on the surface during the summer half year still has a certain amount of energy, it is generally not too cold yet. But the temperature gradually dropped. When the weather is clear and windless, there is often a sunny, warm and comfortable October "Indian Spring" weather.

3. The origin of Lidong

Tracing back to its origins, the ancients’ understanding of “Li” is the same as that of modern people, and it means establishment and beginning. But the word "winter" is not that simple. The explanation of "winter" in the ancient book "The Collection of Seventy-two Hours of the Moon Order" is: "Winter is the end, and everything is collected." It means that all crops in autumn have been harvested. After drying, they are stored in storage and the animals have been hidden for hibernation. Therefore, the beginning of winter not only represents the coming of winter. To put it completely, the beginning of winter means the beginning of winter, the collection of all things, and the avoidance of the cold.

4. The custom of Beginning of Winter

China used to be a farming society. People who worked for a year took advantage of the Beginning of Winter to take a rest and reward their family for their hard work over the past year. There is a proverb, "The beginning of winter makes up for the winter, and makes up for the empty mouth" is the best metaphor. People in northern China, especially Beijing and Tianjin, love to eat dumplings. New Year's Eve is the turn of the old year and the new year, and the Beginning of Winter is the turn of autumn and winter, so dumplings are a must-eat at this time. Nowadays, people have gradually restored this ancient custom. On the day of the Beginning of Winter, all kinds of dumplings are sold very well. In the south, people like to eat chicken, duck and fish at the beginning of winter. On the day of the Beginning of Winter in Taiwan, winter tonic restaurants such as "Mutton Stove" and "Ginger Duck" on the streets are full of customers.
