Since the establishment of Taiping County in Tianbao period of Tang Dynasty, people in Yuan Xian and Gan Tang have been commemorating Xuanyuan Huangdi in the form of "car meeting". Every year from July 18 to 24, ***7 days. From "car washing" and "landing car" test drive, "front car" and "sacrificial car" to "closing the car" and entering the temple, the first car meeting is over. The roller coaster performance takes the big wheels painted bright red as props, takes strength and beauty as the main forms of expression, and is decorated with Jiangnan folk dances, instrumental music, Nuo masks, tattoos and so on. The scene is grand, and the number of people attending the performance ranges from dozens to hundreds. During the day, steamboats and cars run on roads, streets and squares. All ancestral temples, temples, shops and households that can be opened to traffic should roll in front to show good luck and eliminate evil spirits. Every household greeted the car with firecrackers, or dressed the car in red, or killed the rooster and poured blood on the car. There are many "riders" (roller coasters), all of whom are unpaid, and all of them are young and middle-aged men who participate in the games. Rolling methods include: ① flat rolling car, ② hedge, ③ floating car, ④ winding car, ⑤ flapping car and ⑤ spiral car. When the roundabout and the spiral car performed in the square, the drivers and the audience shouted in unison. The sound of gongs and drums and firecrackers shook the earth.

With the changes of the times, the Car Expo has gradually evolved into a large-scale festival gathering with ornamental, interesting and participatory features. Until the eve of the founding of New China, the "auto market" was circulated in huangshan district (formerly Taiping County) for 1200 years.
