Han Deyuan and the four Praetorian Guard sergeants who followed closely followed him continued to walk for less than 100 meters with Han Yu before exiting the Donghua Gate.

As soon as you get out of the Donghua Gate, walk a short distance, and when you raise your eyes, there is a very spectacular palace imitating the Central Plains building: around the palace, the same green tiles and yellow walls; Under the palace, the same nine-step white marble steps on the left and right sides, and the same nine-step five-clawed cloud dragon pattern Dan Majestic stone in the center of the nine-step white marble steps on both sides; Outside the palace, the gate is the same nine rows of copper nails big red palace gate, and the pillars are the same lacquered painted gold silk big nan wood.

The only difference is that this palace is very different from the Central Plains Dynasty in terms of orientation: the palaces of the Central Plains Dynasty are all located south to north.

In the culture of the Central Plains Dynasty, the Son of Heaven is the son of heaven, but the purple star in the sky is in the lower realm, so the position of the Son of Heaven on the earth should coincide with this star in the sky, so the Son of Heaven in all dynasties is respected in the north direction; The palace seat of the Liao State is west to east.

In the legend of the Khitan people, as the ancestor of the Khitan people, the man and woman originally came by white horse and green ox, met at the confluence of the Huang River and the Tu River, and then became husband and wife, so the Khitan people all respect the east.

Standing under the nine steps outside the palace, looking up at the palace, I saw that on the large plaque in front of the palace, the dragon flying and the phoenix dancing were engraved with three huge Khitan characters: Open the Imperial Palace.

It is also a coincidence that during Han Yu's doctoral studies, his doctoral supervisor happened to be an authority on Khitan history research in China and even internationally, Professor Wu Miwu of Nanjing University.

Under the guidance of Professor Wu Mi, Han Yu has a deep understanding of both large and small Khitan characters, and the doctoral dissertation he wrote when he graduated was a study of Khitan characters, so he is no stranger to the three big characters on the Kaihuang Palace.

Han Deyuan saw Han Yu standing in front of the Kaihuang Palace, looking at the buildings here very attentively, only when he had lost his memory and had not recovered, he forgot what place this was, so he stepped forward and asked, "What's the matter, Derang?" Don't you even remember this place? Han Yu shook his head blankly.

Han Deyuan only thought that his younger brother Han Derang had amnesia due to a head injury, so he introduced him in detail and said: "The building of my Daliao Imperial Palace is to draw on the shape of the Central Plains Dynasty, that is, the front hall and the back palace, and the front hall has three major halls, namely the Kaihuang Palace, the Ande Palace, and the Wuluan Palace. As he was talking, a eunuch from the Liao Palace came to deliver the decree: "The lord invites Lang Jun to meet him in Qifeng Tower first." Han Yu listened to Han Deyuan's introduction, there are only three major halls in this Liao Palace, and now he listens to the Qifeng Tower that the eunuch said, he is a little puzzled, because he asked Han Deyuan: "Big brother, where is this Qifeng Tower?" ”
