It may be auspicious, but the number of rooms in the Forbidden City is really amazing. Almost every room in the Forbidden City has windows, and we can judge the identity of the room owner according to the level and pattern characteristics of the flower windows on the windows. This judgment method is also applicable to other palaces.

Gables and sloping roofs

Xieding Mountain has nine ridges, namely one positive ridge, four vertical ridges and four ridges, so it is also called the top of nine ridges. Because both ends of its main ridge break once from the middle of the eaves, it is divided into a vertical ridge and a ridge, which seems to "rest" for a moment, so it is named Xiedingshan.

Inclined peaks can be divided into single eaves and double eaves. The so-called double eave is to add a layer of eaves below the basic oblique peak, which is roughly the same as the second layer of eaves at the top of the temple. Xieding Mountain appeared later than Xieding Temple, and its style was first seen in Hanque stone carvings. By the Song and Yuan Dynasties, the sloping top mountain had become very popular, and the main hall of some buildings began to be changed to the sloping top mountain with double eaves. In the Ming Dynasty, the double-eaved sloping roof mountain was more widely used in temple architecture, surpassing the single-eaved sloping roof temple and becoming the highest-level building after the double-eaved sloping roof temple. In the Forbidden City, Tiananmen Square, Baohe Hall and Kunning Palace all rest on the top of the mountain with double eaves. Zhaodemen, Zhendumen and Dongxiu Palace all use single eaves to rest at the top of the mountain. The use of the rest peak highlights the royal style and strict hierarchy.
