It is customary for people to call opera troupes and troupes Liyuan, and opera actors as Liyuan disciples. How is the pear garden connected with the art of opera? Where is the pear garden? What is its nature? These are all worthy of study. In the early period of Emperor Xuanzong of the Tang Dynasty, the country was unified, the economy was prosperous, and the culture was prosperous. Envoys, scholars, and businessmen from many Asian and African countries gathered in Chang'an. Under the influence of cultural exchanges between China and foreign countries, the music of the Tang Dynasty achieved unprecedented development. Emperor Xuanzong of the Tang Dynasty loved music. In 741 AD, he set aside acrobatic talents who were originally affiliated with the Taiping Temple to set up left and right workshops. He also selected hundreds of good musicians for specialized training in the Liyuan of Caiyuan.

About this art Organizing the establishment of the Liyuan, the Book of Xuanzong in the Old Tang Dynasty records: In his spare time, Xuanzong taught 300 of Taichang's musical disciples to perform silk and bamboo operas, and they were called Emperor's Disciples, also known as Liyuan Disciples. The courtyard was built close to the pear garden of the Forbidden Garden. The New Book of Rites and Music of the Tang Dynasty says: Xuanzong not only knew the music, but also loved French music. He selected three hundred disciples from the Ministry of Arts and taught them in the Liyuan. If the statement is wrong, the emperor will be aware of it and correct it, and he will be called the emperor's Liyuan disciple. There are hundreds of palace maids, who are also disciples of Liyuan, and live in the North Courtyard of Yichun. In the Liyuan Dharma Department, more than 30 people were added to the small department. From then on, the Liyuan became an important artistic activity center in the Tang Dynasty. Where is it? Wang Ji, a man from the Qing Dynasty, wrote in the 37th Jiaofang Liyuan article in the original volume of things: At the foot of Xiuling Mountain in Lishan, Lintong County, Xi'an Prefecture, it is the land of the pear garden. Regarding the origin of Liyuan, it is generally believed that it was originally a place name in Chang'an in the Tang Dynasty, but there are differences on the specific location. Some people pointed out that in the southwest of Chang'an County near Xiangji Temple, today's Liyuan Village of Huangliang Township was first called Liyuan Village or Liyuan Village. Others think it was in the Chunlin Village area next to the former site of Yiyuan built by Emperor Wu of the Han Dynasty near the Qujiang Pool in the southeast corner of Xi'an today. The third theory is that the Liyuan was located in Wumen Village, Sanhuali, near the east side of the Daming Palace of the Tang Dynasty, northeast of present-day Xi'an. The fourth theory states that it was located at the foot of Xiuling Mountain, Lishan Mountain, Lintong County, Xi'an today. Others believe that there were two pear orchards in Chang'an during the Tang Dynasty. Chen Yinke said in the Yuanbai Poetry Notes that one was to the north of Guanghua Gate and the other was next to Penglai Palace. Cihai also held the Liyuan theory, pointing out that there was a Forbidden Garden Liyuan in Chang'an Liyuan in the Tang Dynasty, which was in the Forbidden Garden in the northeast outside Fanglin Gate in the north of Chang'an City; it was the real pear garden in the Tang Dynasty. The Liyuan in the palace is divided into two groups, men and women, all called the emperor's Liyuan disciples

As for the study of the nature of the Liyuan, Cihai said: It was the place where court singing and dancing artists were trained during the reign of Emperor Xuanzong of the Tang Dynasty. The Encyclopedia of Chinese Opera and Music states that during the reign of Emperor Xuanzong of the Tang Dynasty, there was an institution specializing in training musicians in the court, and its main responsibility was to train instrumentalists. Li Youbai proposed: Liyuan is the Royal Academy of Music, Dance, and Drama that not only trains actors but also performs. It is the first comprehensive art academy in my country. Li Longji is its dean. Under him are editors and music camps. Put two sets of people and horses together.

The responsibilities of the former are similar to those of today’s creative staff, while the latter are equivalent to current directors and teachers.

In terms of Liyuan research, the most authoritative one is the Liyuan Examination written by Li Youbai. This book is a comprehensive textual research. Issues related to the Liyuan, and also proposed the establishment of a Chinese Tang Dynasty Liyuan Memorial Hall in Xi'an
