What is the architectural name of the white wall with high black tiles in the south of the Yangtze River?

Horsehead wall, also known as wind-fire wall, accumulation wall, arson wall, etc. In particular, the wall that is higher than the roof of two gables, that is, the top of the gables, is called "horse head wall" because its shape resembles a horse head. In ancient buildings, the roof is divided into front and back slopes by the middle transverse ridge, and the left and right gables are either flush with the roof or higher than the roof. When using the horse head wall, the gables on both sides are higher than the roof, and are horizontally stepped according to the slope of the roof, unlike the common gables, which are isosceles triangles above and rectangles below.

The horse head wall is patchy and has a stylish appearance. Therefore, it is not only one of the commonly used formats of Huizhou architecture in southern China, but also an important modeling feature of Huizhou architecture. There used to be a saying that "a small tile-headed wall hangs a lattice window in the cloister", which was used to summarize the architectural style of Huizhou school in Ming and Qing Dynasties. Generally speaking, beautiful horsehead walls are common in rural areas, but in bustling cities, horsehead walls are extremely rare and precious.
