Why did the ancient emperor set the capital in the north instead of the south?

First, sitting facing south is not only for lighting, but also to avoid the north wind. The topography of China determines that its air is seasonal. There is a cold current in northwest Asia in winter, a cool breeze in the Pacific Ocean in summer, and the direction of monsoon changes all year round. There are records of wind measurement in Oracle Bone Inscriptions. According to Records of the Historian, unhealthy tendencies live in the northwest, and in October. The factory lives in the north, and it is also November. The wind lives in the northeast, and the first month is also. The Ming people lived in the east and in February. The Qingming wind lives in the southeast dimension, also in April. The scenery is in the south, and it is also May. The cool breeze lives in the southwest, and it is also June. Occasionally, the wind will live in the west, and in September.

Second, wind is different from evil wind and yang wind. Dogs can pass through the imperial court's book "Geographical Approval to the South". It is recorded that Pingyang is not afraid of the wind, but there is a difference between yin and yang. It is no harm that the warm wind from east to south is warm and warm, which is called yang wind. The cold wind from west to north is called Ming wind, and there is a blue case. Otherwise, the wind will blow the bones and the family will decline. This means avoiding the northwest wind.

There are several ways to express the orientation of landscape painting: first, five actions are east, fire is south, gold is west, water is north and soil is middle; Second, the height of Bagua is south, the ridge is north, the earthquake is east, but it is west. Third, take Party A and Party B on the calendar as the east, Party D as the south, Geng Xin as the west and Gui Ren as the north. Take the son of the earthly branch as the north and the noon as the south. Fourth, the east is black dragon, the west is white tiger, the south is suzaku, and the north is Xuanwu. Or: Zuo Qinglong, Right White Tiger, Former Suzaku, Later Xuanwu. In short, the principle of facing south is to correctly understand natural phenomena, conform to heaven, gain the aura of mountains and rivers, be influenced by the brilliance of the sun and the moon, care for the body, cultivate sentiment and excel.

Third, in ancient times, the south was regarded as supreme, while the north symbolized failure and submission. The palaces and temples face south, and the emperor's seat faces south. When he became an emperor, he called it "south is the respect"; Defeat, surrender to others, "defeat" and "surrender to the north." It is precisely because the direction of due south is so noble that when people built houses in the past, no one dared to take the direction of due south of the meridian, both east and west, so as not to violate taboos and be convicted.

It's all online. I just summed it up. But I still hope I can help you (* _ _ *)
