New Year's Day is the beginning of the year, but it is not set in stone, and every period in China has its own New Year's Day. The origin and changes of New Year's Day have witnessed the magnificent waves of Chinese history and the 5,000 years of China's continuous progress. 
In ancient China, New Year's Day did not refer to the Gregorian New Year as we understand it today, but to the first day of the first month of the lunar calendar, that is, the Spring Festival. This concept has traditionally been regarded as the first day of the new year, symbolizing the beginning of the year. 
According to legend, New Year's Day and the two emperors of Yao Shun still have a certain relationship. As early as 4,000 years ago in the Yao Shun period, Yao was a Ming monarch, he was very loved by the people, and later, Yao chose the noble Shun as his heir, rather than his own son, which is called "Chan Rang". "Zen rang" is a wise choice, which has also become a model for later generations to follow. In order to commemorate this important decision, people set the day when Shun sacrificed heaven and earth and sacrificed to the first emperor Yao as the beginning of the new year, called "New Year's Day" or "Yuanzheng". 
New Year's Day is the beginning of the year, but as early as the Xia, Shang and Zhou periods, China's calendar has not yet been unified, and each dynasty has its own calendar system: the Xia Dynasty takes spring and January as the first month;The Shang Dynasty took winter and December as the first month;The Zhou Dynasty took winter and November as the first month;After Qin Shi Huang unified China, winter and October were the first month, that is, the first day of October was New Year's Day. During the reign of Emperor Wu of the Han Dynasty, New Year's Day was designated as the first day of the first month of spring, a tradition that remained in use until the end of the Qing Dynasty. 
In this long historical process, New Year's Day is also known as Yuanzheng, Yuanchen, Yuanchun, Yuanshuo, etc., each name represents a page of history, and each page embodies the essence of national culture. These names not only reflect the different names of New Year's Day in different historical periods, but also show the cultural inheritance and innovation of the Chinese nation in the historical process. With the wheels of history rolling forward, the time came in 1911 AD, the Xinhai Revolution led by Mr. Sun Yat-sen overthrew the rule of the Manchu Qing Dynasty and established China. In order to facilitate statistics and adapt to agricultural time, the first year of ** decided to adopt the Gregorian calendar, and the first day of January in the Gregorian calendar was called "New Year's Day". This decision marked an important turning point in China's history, and it also meant that China began to integrate with the world and move towards modernization. 
On September 27, 1949, the First Chinese Political Consultative Conference decided to adopt the Gregorian calendar as the official calendar of China, and officially designated January 1 of the Gregorian calendar as New Year's Day. Since then, New Year's Day has become a festival for the people of the whole country and the starting point of the new year. Today, New Year's Day has become an important festival in China, and is known as China's five traditional festivals along with the Spring Festival, Qingming Festival, Dragon Boat Festival and Mid-Autumn Festival. On this day, various celebrations are held, such as family gatherings, exchanging gifts, setting off firecrackers, etc., to pray for peace, prosperity, and happiness in the new year. 
The origin and changes of New Year's Day are a microcosm of Chinese history, which has witnessed the vicissitudes of Chinese history and demonstrated the spirit of the Chinese nation to keep pace with the times. New Year's Day is not only a symbol of traditional culture, but also a inheritance of national spirit. In the new historical period, we should continue to carry forward this spirit and make unremitting efforts to realize the great rejuvenation of the Chinese nation. - Xiao He
