The title of the New Year's Day handwritten newspaper can be: Happy New Year's Day, Welcome New Year's Day, Happy New Year's Day and other festive names to highlight the festive atmosphere of New Year's Day. New Year's Day is called Yuan Day in "Shu Shun Dian" and Yuan Zheng in "San Zi Chai Ming" by Cui Yuan of the Han Dynasty. It was called Yuan Chen in Yu Chan's "Yangdu Fu" of the Jin Dynasty. An article written in the Northern Qi Dynasty called "Yuanhui Daxianggehuang Xia Ci" as Yuanchun. Li Shi, Dezong of the Tang Dynasty, called it Yuan Shuo in his poem "Retiring from the DPRK to Watch the Army and Return to Camp on the Yuan Day". The month and day of New Year's Day in our country have not been consistent throughout the ages. In the Xia Dynasty, it was on the first day of the first lunar month, in the Shang Dynasty, it was on the first day of the twelfth lunar month, and in the Zhou Dynasty, it was the first day of the eleventh lunar month. After Qin Shihuang unified the six kingdoms, the first day of the tenth lunar month was designated as New Year's Day, and it has been unchanged in all dynasties since then ("Historical Records"). In the first year of Emperor Taichu of the Han Dynasty, Sima Qian created the Taichu calendar, and then the first day of the first lunar month was designated as New Year's Day, which was the same as the Xia Dynasty regulations, so it was also called the Xia calendar, which was used until the Revolution of 1911. After the founding of the Republic of China, Sun Yat-sen followed the agricultural season in order to implement the Xia Zheng. According to the Western calendar, for the sake of statistics, the first day of the first lunar month (New Year's Day) is designated as the Spring Festival, and January 1 of the Western calendar (Gregorian calendar) is regarded as the New Year.
