Qi wall: This is a architectural wonders, and now we see is the rear wall of the palace and the gable, generally now we build the house when the gable and the back wall are mutual bite, but now we see the Yu Wang The walls of the gable and the back wall did not bite, but vertical up to prove that the wall has become a single opposite, it is easy to collapse of the building, but Yu Wangge this building has been almost three hundred years still did not collapse, and Without any repair, people have become architectural wonders. And the reason why the formation of Qi wall there is a story, it is said that when the Emperor Yongzheng ordered the construction of Yu Wangge selected three craftsmen, happens to be three craftsmen is Wu Zhi Xie flag camp three brothers, three brothers started after the discovery of the wall Large area, time and very tight, and finally decided to division of labor, the division of labor is the old base of the old wall, second base of the West wall, the third base of the back wall, three people one side of the wall began to dry, Different, resulting in three different walls of different speed, and ultimately the formation of Qi wall, the people say that because the three brothers do not lead to unite the wall Qi, after the experts identified their walls are very scientific: First, the use of stone reinforcement wall The root of the building, so that the bottom of the building firm; Second, they are very sophisticated construction materials used, we can look at here, in the expert identification results show that this gray for the three gray, there are glutinous rice, mung bean powder, Very strong, so that the brick layer firmly between the stick together to reinforce the walls of the standing, so this building was erect until now.
