Did Emperor Wu of the Han Dynasty have a Spring Festival before?

Yes The Spring Festival is a ritual activity in ancient times. According to records, the people of China have celebrated the Spring Festival for more than 4,000 years, which was initiated by Yu Shun. Spring Festival is called "zai" in Tang Yu, "nian" in Xia Dynasty, "sacrifice" in Shang Dynasty and "nian" in Zhou Dynasty. The original meaning of "nian" refers to the growth cycle of grain, which is hot every year, so the Spring Festival is once a year, which means cool breeze. It is also said that the Spring Festival originated in "La Worship" at the end of primitive society. At that time, whenever the twelfth lunar month in spring came to an end, the ancestors slaughtered pigs and sheep, sacrificed ghosts and gods and ancestors, and prayed for good weather in the new year to avoid disasters. Their faces were painted with vermilion and bird feathers, and they sang, danced, ate and drank, which was very lively. As for the exchange of New Year greetings, it began in the early Han Dynasty and was recorded in Tongdian.

It is said that "Spring Festival" originated from the activities of offering sacrifices to gods and ancestors in the early and late Shang Dynasty in China (La Worship). In the early years of the Western Zhou Dynasty, there was an annual custom of celebrating harvest and offering sacrifices to ancestors at the turn of the new year, which can be regarded as the embryonic form of the year. However, the name of "Nian" appeared late, and the name of Nian began in the Zhou Dynasty. When the ancient emperors inherited the throne, they often stood on their own calendars in order to show the authority of the "son of heaven". It was not until the Western Han Dynasty that the year 2000 was officially set, and it has continued to this day. Emperor Wu of the Han Dynasty (140 ~ 87 BC) succeeded to the throne and decided to rebuild the calendar unification. Sima Qian suggested the establishment of taichu calendar, and the Spring Festival was held in the first month of Meng Chun. The calendar we adopt today has been revised by many dynasties since Emperor Wu of the Han Dynasty, but the first day of the first lunar month, as the most solemn festival of the Chinese nation, has been inherited as a fixed day.
