The so-called "front yard and back bedroom" means that the palace is divided into two areas: front and back. The front area is called "Chao", where officials of the imperial court handle government affairs, and the back area is usually called "harem", where the royal family, ladies-in-waiting and eunuchs live and live. In today's words, the front is the work area and the back is the living area.
The Forbidden City in Beijing is bounded by the Gan Qing Gate. A long partition divides the whole Forbidden City into two areas: the former dynasty and the later dynasty.
The so-called "five doors and three dynasties" was stipulated by the ancient court system. There must be five gates in front of the palace, namely, Gaomen, Kumen, Luomen, Yingmen and Liumen. There should be three imperial courts of the emperor, namely, the foreign dynasty, the ruling dynasty and the Yan dynasty. In today's Forbidden City in Beijing, the corresponding five doors are Daqianmen, Tiananmen, Duanmen, Wumen and Taihe. These three dynasties are the three halls in the Forbidden City-Hall of Supreme Harmony, Hall of Zhonghe and Hall of Baohe.
Historical evolution:
In the history of more than 2,000 years in China, hundreds of emperors have emerged, and almost every emperor has built a grand, luxurious and magnificent mausoleum, which is built on auspicious soil and geomantic treasures.
In the emperor's mind, the two are equally important. In the eyes of the world, it seems that people tend to pay more attention to the palace and despise the imperial tomb. That's understandable. From the perspective of historical research, the importance of the imperial tomb is not worse than that of the imperial palace, or even more valuable. A palace can be used by many emperors or even several dynasties.
