What did the ancient emperors use to lay the floor when they went to a certain place? Reading the novel Li Zicheng, I wrote that Li Zicheng went to Beijing and paved the floor with yellow sand. There is no relevant content on the internet, and there are typos.

Generally speaking, the emperor visited the official road, but it was actually an ancient national road. Out of the city, it's all yellow land. Only near the edge of a town or a big city will there be a short circuit paved with blue bricks. If the emperor goes out into the wild, it is actually yellow land.

As for the part of Li Zicheng, in ancient times, when preparing for the reception, there was a saying that "the loess paved the floor and the streets were splashed with water". Whether it's yellow sand or loess, it's just to smooth the uneven places so that the water can't sprinkle dust (many people in ancient times had a lot of dust when riding horses or sitting in sedan chairs).
