During the Yao and Shun period, people regarded the day when Shun Di offered sacrifices to the first emperor Yao as the beginning of the New Year, and stipulated that the first day of the first month was "New Year's Day". Before the Han dynasty, the time of the first month often changed with the change of dynasties. In the Han Dynasty, Emperor Wu of the Han Dynasty officially designated Meng Xiyue as the first month. The first day of Meng Xiyue was called New Year's Day, and this calendar continued until the end of the Qing Dynasty. After the founding of the Republic of China, the central government decided to adopt the universal method of AD chronology, stipulating that 1 month 1 day in the lunar calendar is the Spring Festival and 1 month/day in the solar calendar is the New Year.

After the founding of the People's Republic of China, the new China adopted the law of the first year of the year, and designated January 1st of the Gregorian calendar as New Year's Day. Therefore, as the first day of the Gregorian New Year, New Year's Day actually has a history of only 70 years.

The moral of New Year's Day:

Every year 1 month 1 day is New Year's Day, which is the beginning of the new year. "New Year's Day" is a compound word. According to a single word, the word "Dan" is represented by a round sun. The word "one" below "Day" represents the horizon, which means that the sun rises from Ran Ran on the horizon. It symbolizes new life and is a kind of hope for the rise of Ran Ran.

The customs of New Year's Day are as follows:

The winter weather in northern China is cold, with short days and long nights. Starting from New Year's Day, the people who are idle in farming kill pigs and sheep, sit cross-legged on the heatable adobe sleeping platform, talk about their families, do not work, and do not go out until the fifteenth day of the first month. Due to the cold weather, the northeast New Year's Day is mainly based on diet.

The custom of New Year's Day in the south tends to be "elegant". In Jiangsu and Zhejiang provinces, bamboo poles are tied to grass and ignited on New Year's Day, which is called "according to the field silkworm".

In Taiwan Province, a treasure island, on New Year's Day, the whole family, old and young, will gather together for dinner and put hot pot on the table, which is called "around the stove". Those who take part in the "fireplace" should taste everything on the table and drink symbolically to make the next year prosperous.
