The answer is yes, obviously not allowed, it should be said that people can't live. In ancient times, the construction of palaces and tombs was very particular about geomantic omen. Generally speaking, palaces and tombs are located on the land of Long Mai. If the location of the palace is based on the basic layout of geomantic omen, the northern part needs high terrain and mountains, and the southern part needs squares to broaden the so-called famous halls. The north of the palace must be dominated by round stones. Will not live completely in the northern part of the palace. And the palace, where a country's great wealth lies, lives too close to the palace. In fact, for those who live in it, it is not necessarily a great fortune, but more likely to be robbed by the palace. Therefore, if you live in the ancient imperial city in terms of geomantic omen, your life is not good, your life is not hard enough, and your aura is not enough, you should not live. On the contrary, you are more likely to be beheaded or bankrupt there.
In non-war times, the palace is also guarded. The so-called Kingsguard and the so-called Wu Jindu are Royal Guards. Directly under the management of the emperor. So this includes all the city walls, the gates in and out, as well as daily patrols and garrisons.
