As one of the ancient official residence tourism lines in China, Huozhou Department, the central axis is intact, and you can feel the momentum at that time. Please explain 30 yuan once. You can better understand the official residence culture. It is like "one word enters the public door, nine cows can't pull it", which means that the complaint should be written on paper. But the paper must be written very rigorously, if you write a wrong word to submit it and find that the meaning is wrong, it is impossible to take it out, so there is a place to help write the paper at the door to avoid writing mistakes; There is also the plaintiff stone, the original plaintiff is to kneel in a special place, can not kneel casually, for a long time, you can find the plaintiff kneeling place has two very deep knee marks, this is how many people to kneel will have this effect; There is also a screen in the second hall behind that can be opened in the middle, in order to let the emperor pass through the hall. These allusions, without explanation, will not know so clearly, very good official travel experience
