Zhou said that this place is in the middle of Helan Mountain, which is an extension of "Wolong Huaizhu", and predicted that "there must be emperors and princes" here in the future, so Han Yu decided to build a fort here, which is now Zhenbei Fort. Throughout the ages, there have been no emperors and princes here, but there have been many film and television works, stars and famous directors that have sensationalized the world cinema. In the Qing Dynasty, in order to prevent foreigners from taking advantage of it, an earthen fort, which was slightly larger than the "old castle", was built less than 200 meters away from the destroyed "old castle", and it was called "new castle". It was completed about two years after the castle was destroyed by the earthquake, that is, five years after the Qing Dynasty (1740), which has been a long time since. This kind of old castle, commonly known locally as "earth enclosure", is a unique "earth-covered building" in northwest China. The ancients also paid attention to local conditions and local materials. The castle walls are completely rammed with loess without bricks. After hundreds of years of rain, snow, wind and frost and man-made destruction, by the fifties and sixties, the majestic posture of the frontier fortress had disappeared. Different people have different opinions.
