Sima Yan, Emperor Wu of Jin Dynasty, established Luoyang as the capital and made some progress. However, the "Eight Kings Rebellion", "Five Rebellions" and other civil strife and foreign invasion frequently occur one after another. In the fifth year of Yongjia (3 1 1), the Xiongnu captured Luoyang, and the royal family and bureaucratic groups fled south one after another. In the Western Jin Dynasty, Luoyang was reduced to ruins in just 46 years, which was called "Yongjia Change" in history.
During the Northern and Southern Dynasties, Tuoba Group established the Northern Wei Dynasty with Luoyang as its capital. At this time, Luoyang City is located near Jin Meng and Yanshi, about fifteen miles east of Luoyang City. Here is a treasure trove of geomantic omen: Mangshan Mountain in the north and Luohe River in the south, with superior natural conditions. Luoyang, the capital of the Northern Wei Dynasty, has a different architectural style from the previous Han and Wei Dynasties. The form of this city is the outer contour, the inner city and Miyagi. Build an outer profile on the east, west and south sides of the inner city. The innermost Miyagi is the center of the entire capital of Luoyang.
The Northern Wei Dynasty was a regime ruled by ethnic minorities, but most of it had been sinicized. Emperor Xiaowen of Wei (467 ~ 499) worshipped Chinese culture very much, so the management of the capital was relatively standardized. The inner city is basically the same. To the north of Miyagi is the Royal Garden, namely Hualin Garden. There are three small towns in the northwest of the inner city, named Jinyong City, which are meticulously built and can be described as impregnable. They are the military sites of Luoyang capital. Buddhism flourished in the Northern Wei Dynasty, and there were quite a few Buddhist temples (pagodas) in Luoyang metropolitan area. At most, there were more than 1000 temples, some of which were very large. The most famous tower is Yongning Temple, "90 feet high", which is somewhat incredible.
