Why are there so many "buns" and "Zi Ying" in Ningxia? How is it formed?

"Bao" has three pronunciations, most of which are pronounced as "b incarnation" in the northwest, referring to villages and towns with walls. The most famous is Bao Bei Film and Television City in Yinchuan Town. Historically, Ningxia has four mountains and rivers, and there are many castles and villages, which is a major historical landscape of Ningxia as a northwest frontier region. Nowadays, the place names of ancient villages and towns are synonyms for the names of ancient castles. With the changes of the times, the names or synonyms of these castles, large and small, have been preserved, but most of the ancient castles have been demolished and withdrawn from the historical stage because of the loss of their functions. Several preserved ancient castles have been developed into tourist attractions, and some older castle sites and remains are still silently telling the glory of the past in the erosion of historical storms.

Most places with the above names in Ningxia have seen fortress buildings with high walls and thick walls in history. Even in today's ancient city of Yinchuan, in the early days of the founding of the People's Republic of China, there were still five fortresses distributed along the street, with rammed earth slabs as high walls, so-called "big cities and small towns". As for all the mountains and rivers in Ningxia, except a few so-called "big cities" that can be called county towns, all the places where people live together are fortresses. Villages in the modern sense are generally scattered along rural roads, which did not exist in the history of Ningxia. As soon as the "big city" comes out, it is the countryside. Looking around, in addition to empty fields and wasteland, there are fortress buildings with different distances, sizes and similar shapes. The famous family in Yongning County turned out to be a fortress with thick walls. The name of the fortress is "that household", and everything has its own voucher-style fortress door. Before 1958 was demolished, there were more than 120 people with that surname, with a population of nearly 1000. The famous Wuzhong Fort in Hedong was named after Wuzhong, a guerrilla general of the Ming Dynasty. According to the summary of Ningxia released by 1947, there are 3,000 households in the castle, most of which are * * *. The famous Journey to the West was filmed in Zhenbeibao Film and Television City. As for the place names of ancient villages and towns in Ningxia, without exception, they are all named after ancient castles, some are named after landforms, some are named after people, and some are named after functions. Such as Hongshanbao and Qingshuiying, named after Hongshan and Qingshuihe; Zhang, Li Junbao and Wang Hongbao are named after people. Pingqiangbao (Pingjibao), Zhenbeibao and Dingrong Village are named after their functions. Nowadays, village-level units are all ancient place names, which are the locations of large and small forts of folk buildings in history. Most of them are named after the surnames of the owners of the forts, such as Majiapuzi, Zhangjiazhaizi, Fanjia Zhuangzi and Lijiayingzi. Baozhai architecture in Ningxia has a long history. It can be traced back to the Western Han Dynasty. In the early years of Emperor Wudi's yuanshou, a large number of Han people in the Central Plains migrated to the Hetao area, including Yinchuan Plain in northern Ningxia, to enrich the frontier, open canals to cultivate fields and dig valleys. In Ningxia Plain, which has always been the activity area of nomadic people in the north, castles in wasteland, large and small, have appeared one after another to accommodate immigrants. They build houses in villages in the city, which are sheltered by high walls, sheltered from the wind and sand, with little external interference, safe and reliable, and the people enjoy it. In the later dynasties, some castles developed into cities, while most castles were preserved to avoid frequent wars and defend against bandits like hemp, which became the homes of people of all ethnic groups in Ningxia and the support of concentrated residential buildings in Ningxia. Therefore, Ningxia has formed an architectural tradition and has been able to continue it. In the Ming Dynasty when * * * was formed, there were frequent wars in Ningxia. Due to military needs, in addition to the fortress buildings that have been preserved throughout the mountains and rivers in history, a large number of small castles have been built for garrison defense, and most of them are named after civil and military officials. As for folk castles, it is even more difficult to count, and most of them are named after their owners. Later, the castle lost its function of military defense, and the locals built low-walled courtyards and houses in the castle to live in. However, the adobe houses built in these castles, large and small, are still the mainstream of folk houses in Ningxia. Later, due to the interference of war, the scattered fortresses, stockades, camps and Zhuangzi in Ningxia Plain were all empty after the people moved to Guanzhong, Shaanxi Province in the early years of Ming Hongwu. However, after the war subsided and the people returned, these castles were still inhabited, which provided space for Hui-Han dwellings in Ningxia. In a bunker in Zhangjiakou, there are people with mixed Han nationality, people who live in pure Han nationality and people who live in pure * * *, so there is a folk saying that "* * * lives in the bunker and * * * has * *". In the Qing Dynasty, that Hu Temple was still building houses in Baozhai, where the Han people lived in Ningxia. The so-called "Fifty-sixth Fort in Haicheng County (now Haiyuan County)", "Thirty-eight Fort in Pingluo, More than 500 Fort in Dolly" and "Ninety-seven Fort in Ningxia (now Yinchuan)" are vivid portraiture of the architectural condition of the fort in Ningxia in the middle and late Qing Dynasty. Fortress-style buildings surrounded by high walls and rammed earth boards did not gradually disappear from people's sight until the 1960s. At present, there are less than 100 preserved "old castles" and their sites in the mountains and rivers of Ningxia. Source: Network
