The design concept of the Palace Museum is based on the trinity of Zhouli, Yijing and geomantic omen. In terms of the overall layout, it can completely integrate heaven, earth and human beings to reflect the way of universe generation. Combining Zhouli, Yijing and the three forbidden cities built by Fengshui together is a complete forbidden city.

The buildings are arranged along a north-south axis in strict accordance with the rule of symmetry, and the buildings on this axis are centered on the Forbidden City. They all face south, reflecting the emperor's supremacy.

From the layout of the Palace Museum, the palace city is divided into two parts: the former dynasty is divided into three main halls, Taihe hall, Zhonghe hall and Baohe hall, which are the place where the emperor listens to the government and holds the grand ceremony, while the latter two are the place where the Emperor Yan sleeps.

The temple of Jiaotai is the dragon's cave in the Forbidden City.

The basic feature of China's terrain is that it is high in the West and low in the East, and it gradually declines from west to East, showing an obvious inclined ladder. The whole trend is higher in the northwest and lower in the southeast.

The Dragon veins of the Forbidden City are located on the Beigan dragon vein, one of the three major dragon veins in China. They are bounded by the Yangtze River and the Yellow River. The north of the Yellow River is called beiganlong, the south of the Yangtze River is called nanganlong, and the middle of the Yangtze River and the Yellow River is called zhongganlong.

From Kunlun mountain to Yanshan mountain, this huge mountain range stretches across the north of China and is the strongest natural barrier. The dragon vein gas from Kunlun Mountain is all condensed in the backers of Tianshou mountain Forbidden City, where the dragon vein gas stops to form a cave.

Jiaotai hall, located between Qianqing palace and Kunning palace, is the acupoint of the Forbidden City. The Qianqing palace symbolizes heaven, while the Kunning palace symbolizes land acquisition, because Qian is heaven, heaven is Yang, Kun is earth, and earth is Yin. The way of heaven and earth is the way of yin and Yang. Moreover, the combination of Qianqing palace and Kunning palace is the "Tai" hexagram. The former Jiaotai hall means that heaven and earth are in harmony with each other in order to realize the ideal of "harmony between heaven and earth".

A group of brothers of the Mu family, listening to Chu muyue not only explain the history of the Forbidden City for them, but also talk to them about the connection between the Forbidden City and geomantic omen gossip.

When walking out of the Palace Museum, the brothers of the Mu family all admire Chu muyue, a young girl.

It's also because of their admiration that they feel useless. When they come back to Mu's home, they are all dejected. Seeing their appearance, Mu HaiYe asks suspiciously, "eh? What happened to all of you? "

Chu muyue looks at the appearance of Mu Yutao and others and feels his nose awkwardly.

She didn't mean it, really! They said they wanted to hear. That's why she explained.

Mu Yifeng looks up at his father Mu HaiYe, who is still depressed. Then he looks at Chu muyue and rushes to the sofa. The whole person is buried in the sofa.

"What's the matter?" When Mr. Mu saw that all the boys in the Mu family were like this, he was puzzled.

Chu muyue also did not speak, went to the side of master Mu and called, "grandfather!"

Master Mu touched Chu muyue's head and said softly, "are these stinky boys bullying you? I'm afraid that's what you're going to tell me? "

Mu Haixuan a listen, don't believe of say, "shouldn't?"

Only mu Ziheng didn't hit hard. He looked at Chu muyue and said, "originally, we should have taken muyue's elder sister to visit the Forbidden City, but when we got to the back, it was muyue's elder sister who introduced us to the Forbidden City. The stories and legends are very vivid!"
