Pingju was originally called "Bengbeng Opera", "Luozi Opera", also known as "Pingqiang Bangzi Opera", or "Ping Opera" for short. The name "Pingju Opera" was officially used in 1935. It is popular in Beijing, Tianjin, Hebei and Northeast China, and has a broad mass base. Around 1910, Bengbeng Opera artists headed by Cheng Zhaocai absorbed the singing music and performance art of Northeast Errenzhuan, Peking Opera, shadow puppetry, and drums on the basis of the counterpart "Lotus Fall" in Luanzhou, eastern Hebei, and used a full set of Hebei Bangzi musical instruments to accompany the performance, forming the basic style of Pingju Opera. In the process of practice, the emerging Pingju Opera art has been continuously developed and improved, and has become more and more mature. Cheng Zhaocai is the founder of Pingju Opera and the first playwright of Pingju Opera. His representative works such as "Ma Widow Opens a Shop", "Flowers as Matchmakers", and "Yang Sanjie's Complaint" have become classic repertoires of Pingju Opera. Pingju music belongs to the Banqiang style, including "Jianban", "Daban", "Da'anban", "Xiao'anban", "Sanchui", "Daoban", "Duoban", "Liushuiban" and other styles, as well as counter-tune. Accompaniment instruments are divided into three types: stringed, percussion and wind. Stringed instruments include banhu, erhu, sanxian, etc., percussion instruments include ban, bottom drum, hall drum, bottom gong, big gong, etc., and wind instruments include flute, suona, etc. Pingju singing style draws on the music of Peking opera and bangzi, and is divided into male and female styles. China Pingju Theater inherits the traditions of Xilu Pingju and Donglu Pingju, and retains many contents of Beijing's traditional culture in the performance. At the same time, it inherits, develops and forms artistic schools such as Bai (Yushuang), Xin (Fengxia), Wei (Rongyuan), Sun (Defu), Ma (Tai), etc. Tianjin Pingju Theater is also very strong, and has a good inheritance and development of the four major schools of Li (Jinshun), Liu (Cuixia), Bai (Yushuang) and Ai (Lianjun). With the changes of the times, the influence of Pingju Opera is greatly weakening, and measures should be taken to provide it with necessary protection and support.
