Liyuan was originally a place name in Chang 'an, the capital of the Tang Dynasty. Because Li Longji, the Emperor Xuanzong of the Tang Dynasty, taught and performed art here, it was later associated with traditional Chinese opera art and became synonymous with art organization and art. According to legend, Li Longji, the early Emperor Xuanzong of the Tang Dynasty, was a lover of opera and music. He not only loved listening and appreciated it, but also sang two songs, played musical instruments and directed rehearsals. He loved large-scale songs and dances, so the emperor presided over and selected 3,000 musicians, and often personally visited and guided them, and concentrated the artists in the pear garden in the palace for drills. Later, people used the "Liyuan", a training venue provided by the emperor, to refer to the opera music industry.
