Construction concept of Luoyang city site in Sui and Tang Dynasties

Luoyang City in Sui and Tang Dynasties was designed and built by Yuwen Kai. Yu Wenkai perfectly combined the planning and design of Luoyang city in Sui and Tang Dynasties with Luoyang landscape, and truly realized the planning concept of harmony between man and nature. Yu Wenkai decisively changed the traditional symmetrical urban layout in China, making the city unique and connecting all parts of the city with the emperor. Take the flowing water of Luoshui as an analogy to the Tianhan Galaxy in the sky, and regard the capital as the "Wei Zi Palace" of the Emperor of Heaven. The largest bridge on Luoshui is connected with the main entrance of Gongcheng South, and is called "Tianjin Bridge". Tianjin means a port in the celestial world, where ships will stop and sail for the Galaxy: "Draw Luoshui across the capital, such as Tianhan (Galaxy), and cross the bridge to the south (Tianjin Bridge) to reach France. Dingdingmen Street in Luoyang, connecting the main entrance of Miyagi and the "Dingdingmen" Imperial Road at the south gate of Guocheng, is 1 10 meters wide. " Tianjie means the street of the son of heaven, corresponding to the constellation Tianjie in the sky.

During the Sui and Tang Dynasties, the southernmost axis of Luoyang Imperial City was opposite to Longmen, which made the south gate of Miyagi and Imperial City opposite to Longmen, and arranged Miyagi in the northwest of the capital with the highest terrain, symbolizing the Polaris in the center of the sky. Therefore, Miyagi in Luoyang City in Sui and Tang Dynasties is also called "Wei Zi Palace". The central axis complex of Luoyang City in Sui and Tang Dynasties was the most magnificent central axis in ancient China.
