Northern Kunqu Opera, referred to as "Beikun" for short, is a branch of Kunshan Opera in ancient China. Mainly popular in Beijing, Tianjin and central and eastern Hebei. Because of its long-term joint performance with Yi cavity (high cavity), it is called "Kun Yi cavity". After the Revolution of 1911, it was once called "Levin Kunqu Opera", but it was renamed today after the founding of the People's Republic of China. During the Wanli period of the Ming Dynasty (1573- 1620), Kunqu opera had spread to the north. In the early Qing Dynasty, Kunqu Opera clubs and artists in Jiangsu continued to perform in the north. The Qing government once called Kunqu Opera "Ya Bu" and moved it to the Forbidden City. After Qianlong and Jiaqing (1736- 1820), Qin Opera, Huizhou Opera and Han Opera, known as "Flower Department", entered Beijing one after another, and Kunqu Opera gradually declined. During the Daoguang light-year period (182 1- 1850), there was no pure Kunqu opera society among the people. Some of them returned to the south, and some of them belonged to Huiban and cooperated with Pi Huang artists, and later developed into the "Jingkun" school in Beijing Opera. On the other hand, Kunqu Opera and Yi Opera (high notes) performed on the same stage, developed to the central and eastern Hebei, and merged with local folk artists, gradually forming a branch of northern Kunqu Opera. In the early years of Tongzhi (1862- 1874), Yi Huan, the prince of alcohol, set up an Anqing class (later renamed Ban) in his mansion and also sang Kunqu opera and Yi. In the 16th year of Guangxu (1890), Prince Chun died and Enrongban was dissolved. Most artists returned to their hometown, moved around their hometown and taught a large number of children. In the early years of the Republic of China, although the political situation was chaotic, the northern Kunqu opera also developed greatly. At that time, famous Kunqu opera actors, such as Wang Yiyou, Zhu Yizheng and Hao, still performed two kinds of Kunqu opera, but Kunqu opera was more than Yi opera. 19 17, famous Kunqu artists Hou Yilong, Ma and Han Shichang came to Beijing to perform. Among the actors are Guo Penglai, Tao Xianting, Chen Ronghui and Zhu Xiaoyi. Later, Wang Yiyou, Hao, Hou Yushan and Wei Qinglin also joined in, and the lineup was relatively neat. Moreover, because Rongqingshe is specialized in performing Kunqu Opera, with the assistance of famous composers and Peking University professors Wu Mei and Zhao, and introduced by the press, it has caused great influence in the society, and Han Shichang has gained a high reputation. 19 19 After the May 4th Movement, Rongqingshe performed in Shanghai and other places. Since then, they have toured in large and medium-sized cities such as Beijing, Tianjin, Shanghai and Nanjing in the name of Rong Qing Society and Qing Xiang Society. 1924, due to the coronation of the Emperor, Japan invited Han Shichang and others to lead some members of Rong Qing societies to perform in Tokyo and other places. In addition to the original cast, young actors such as Hou Yongkui and Ma Xianglin have also been added. In the same year, Bai Yunsheng established the Qingsheng Society and performed in Beijing, Tianjin and Bulgaria. With the support of Beijing Opera, he communicated with Beijing Opera and expanded the influence of Kunqu Opera. From the end of 1920s to the beginning of 1930s, the northern Kunqu opera was hit repeatedly, especially in 1938, when Tianjin was flooded, many famous artists such as Tao Xianting and Hou Yilong died one after another, and the northern Kunqu opera suffered serious losses. After War of Resistance against Japanese Aggression's victory, he met with Han Shichang, Hou Yongkui, Ma Xianglin, Hou Yushan, Wei Qinglin, Bai, Hou Bingwu, etc. In Beijing, and once again formed the Qingsheng Society to perform in theaters such as Jixiang and Hua Le. Later, due to the small audience, they were forced to disperse, some jumped ship to make a living, and some performed with Beijing opera, but it was difficult to recover their bad luck. On the eve of the founding of the People's Republic of China, Beikun.
