According to the introduction of Zhuang people in Du 'an and mashan county, in the past, pole dancing was not to knock on the bench with a pole, but to knock on the wooden mortar with a pestle (a big wood was hollowed out in the middle to pound rice), so Zhuang language was also called "drum wave".
Liu Yao, a Tang Dynasty man, wrote in the Record of Ridges: "There is a mud hall in Guangnan, with mud wood as the trough, and there are about ten ridges on both sides of the trough, which stand between men and women, with rice grains and strings knocking on the trough, all of which are biased. If the groove sounds like a drum, it can be heard for miles. Although I think that the hostess is clever at using the autumn anvil, she can't be brighter than it. " It can be seen that the "pound hall" in the Tang Dynasty is a vivid portrayal of the meter-pound labor of the ancient Zhuang people. With the development of history, it gradually evolved into today's pole dance. The rice-beating dance still popular in Debao County, the rice-beating dance in Pingguo County and the well-drilling dance in Ningming County have basically maintained the characteristics of the ancient "rice-beating hall". Because the loud sound of the trough indicates the bumper harvest and prosperity of the dealer, there is a proverb that "the first month of the church will be full of noise, and crops will be abundant everywhere this year."
