Acrobatics was included in the "Hundred Dramas" in ancient times, which was the general name of ancient music, dance and acrobatic performances in China. Acrobatics is a broad concept here. Later, with the increasingly fine division of labor, "Hundred Dramas" gradually divided into acrobatics, magic, song and dance, folk art, drama and other categories with their own artistic personality.

In modern times, what we usually call acrobatics refers to a narrow category. Performances can be roughly divided into stage acrobatics, aerial acrobatics, magic, animal training, circus and funny performances.

In ancient times, acrobatics was once regarded by feudal dynasties as an important means to show off the national prestige of Wushu, and there was a grand occasion of "various acrobatic performances, harmony between the ruling and the opposition". However, with the strengthening of feudal autocracy, acrobatics and folk artists in rivers and lakes were degraded and regarded as "beggar art". Acrobatics artists were humiliated and forced, and acrobatics itself was destroyed. After the founding of the people's Republic of China, under the guidance of the party's policy of "letting a hundred flowers blossom", acrobatic art has been developing continuously; Shandong acrobatics not only inherits the traditional superb skills, but also embodies the unique artistic style and distinctive local color of Qilu acrobatics. Many outstanding innovative art festivals have not only won the first prize in China, but also won the gold medal in the International Circus Festival, which has made great contributions to Shandong's foreign cultural exchanges.
