The geomantic thought of the Forbidden City reflects the grand cosmic thought of the ancients. The Forbidden City is connected with Kunlun Mountain through Long Live Mountain, Jinshui River, Tianshou Mountain, Yanshan Mountain and Taihang Mountain. Through the mountains, introduce the vitality of the sky into the Forbidden City and hide it at the intersection of heaven and earth. This is the way the Forbidden City universe was created, that is, "Qi". In the sky, Polaris is the center, and all the stars are arranged around it. The central axis of Beijing runs through the city, so that all the mountains and rivers in the world are distributed around it. The emperor sits in the Hall of Supreme Harmony, like Beichen crossing the sky and "listening to the world in the south". This is the cosmic structure of the Forbidden City. Beijing is divided into east and west parts, with the sun in the east, the sun in the west, the hall of supreme harmony as the center, the sun in the left, the sun in the right and the sun in the right. This is the time and space of the Forbidden City. The Forbidden City consists of five elements: earth in the center, water in the north, gold in the west, fire in the south and wood in the east, so the palace was built. The six palaces in the palace are built according to the six hexagrams, and the seven palaces in the east and west are listed according to the seven stars in the north. It is located in four directions of the Forbidden City, with four Yang hexagrams in the east and four Yin hexagrams in the west, forming the two major residential areas of Yin and Yang in Beijing, and is the cosmic building of the Forbidden City. People live in it and are connected with the universe:
"The air flow between heaven and earth turns!"
This is the environment in which our ancients lived.
The concept of building cities and tombs by geomantic omen can bring mountains and rivers, architecture, orientation and naming into the overall planning. Beijing is centered on the Hall of Supreme Harmony, which is integrated with the Temple of Heaven, Ditan, Chongwen Gate and Xuanwu Gate, while Beijing is integrated with Jinshui River, Tianshou Mountain and Yanshan Mountain, thus encompassing everything in the world. Buildings in the city, the direction of rivers, the naming of palaces and so on. All of them have been carefully designed by Feng Shui master (different from modern architects), which can penetrate into the world and become a part of people's lives. On the other hand, the mystery of the city is precisely because of its mutual infiltration with heaven and earth, and many places cannot be changed, including the buildings that affect people's travel.
