However, the origin of Mid-Autumn Festival began in the Tang Dynasty. According to legend, during the Tang Dynasty, Emperor Xuanzong of the Tang Dynasty sleepwalked in the Moon Palace, and when he came back, he designated August 15 as the Mid-Autumn Festival. In addition, 65,438+00 days before August 15 is the birthday of Emperor Xuanzong of Tang Dynasty. Therefore, in order to promote the Mid-Autumn Festival, the Tang Dynasty spared no expense in giving welfare to officials, so that people all over the country could experience the joy of the Mid-Autumn Festival.
This festival was quickly accepted by the people of the whole country. It is said that Tang Xuanzong brought back colorful feathers when he was sleepwalking in the Moon Palace. At that time, Tang Xuanzong was fascinated by this song, so he also took this song as the representative song of Mid-Autumn Festival. After hearing this song in the Moon Palace, Emperor Xuanzong secretly recorded the beat and brought it back to his musicians for creation. At first, it was only for the nobles in the court to enjoy, but with the continuous spread of Tang Wenhua, many folk literati also had access to this piece. Everyone thinks that the melody of this piece is beautiful, and it can also meet the theme of Mid-Autumn Festival. Therefore, this piece of music spread rapidly among the people, and many folk literati began to play and appreciate it, which also made Caiyu the most representative musical work in the Tang Dynasty. This piece of music became famous all over the world with the Mid-Autumn Festival.
But after the prosperous Tang Dynasty, the Tang Dynasty gradually declined, and this song was gradually lost. Today, only the Mid-Autumn Festival has survived.
