Acrobatics is the general term for traditional folk performing arts in my country. Beijing Tianqiao has a long history and is one of the important birthplaces of acrobatics in my country. It is home to many acrobatics artists with distinctive characteristics and superb skills. Zhu Guoquan is an old Tianqiao artist who is famous for his hard qigong, martial arts and magic whip performances. His performances are vigorous and wonderful. Like Zhu Guoquan, the five brothers and sisters of the Cheng family who perform in Tianqiao are famous for their small martial arts. Their performances are steady and solid, and their movements are beautiful, forming their own school. In 1970, Song Xiulan's father met Zhu Guoquan who was sent down to Fangshan. Since then, Song Xiulan and her siblings began to learn traditional acrobatics. The Song brothers and sisters practiced martial arts and hard qigong with Zhu Guoquan. Later, with the introduction of Zhu Guoquan, they followed Cheng Lianbao to learn Cheng's small martial arts. The performances of the Song brothers and sisters have been passed down from the two teachers. The Song brothers and sisters are the heirs of Zhu Guoquan's hard qigong performances, and can perform traditional "double wind piercing the ears", "nail board lying fork", "silver throat", "sword piercing the throat" and so on. The Cheng brothers and sisters' martial arts performance is unique, emphasizing that in their respective body movements, the five people cooperate tacitly to complete a beautiful overall shape, with skillful and clean movements. Five of the Song brothers and sisters followed Cheng Lianbao to learn martial arts, with coordinated and unified movements and beautiful shapes, and they have mastered the essence of Cheng's martial arts. The Song's acrobatics is a district-level intangible cultural heritage project in Fangshan District. It inherits the performance characteristics of the old artists of Tianqiao. It has important historical and artistic value for the study of acrobatic performances. At the same time, it also has a certain social role in foreign cultural exchanges. In recent years, as the Song brothers and sisters are getting older, they are committed to organizing the performance skills of teachers Zhou Guoquan and Cheng Lianbao into written materials, and at the same time recruiting acrobatics students to better pass on the two performance skills of hard qigong and martial arts.
