There are two opinions about the date of Yulin City's establishment: one is the early years of Hongwu in Ming Dynasty (1370 or so); Another view is that the Ming Dynasty was orthodox for two years (1437), with a difference of more than 50 years. In fact, before the Ming Dynasty, there was an elm forest and a clear spring on the hillside. People surrounded the spring with trees, and a natural village called Yulin Village was formed. At the beginning of the Ming Dynasty, the residents who had just experienced the war naturally became cautious. For safety reasons, they expanded the village into a stockade with a little defensive function. This is the origin of the first statement. The stockade needs constant reinforcement, and more and more residents will move earth and stone to build the city wall in the next two years, which will prove the founding of Yulin City. 14 (1449), Yulin Castle was built to resist the frequent invasion of Mongolian cavalry in the north. In the seventh year of Chenghua (147 1), Yulin Wei was established and Fort was changed to Acropolis. At that time, Wei established a first-class military establishment under the town to manage the army and local fortifications.
With the changes of villages, stockades, castles and sanitation, Yulin is playing an increasingly important role in regional military and political affairs. In the early Ming Dynasty, there were only four towns in China: Liaodong, Fu Xuan, Datong and Yansui. Later, Jizhou, Ningxia, Gansu, Guyuan and Taiyuan became nine towns, which were called nine important towns in history. Nine years of Chenghua (1473) is an important year in Yulin history. This year, Yu Zijun, the mayor of Yansui Town, moved the town from Suide to the north and began to take Yulin as the town name. Yulin thus became one of the nine major military towns of the Great Wall in the Ming Dynasty. Yu Zijun, a native of Sichuan Qingshen mentioned here, made great efforts to govern the country during his tenure in Yansui. His greatest contribution is to build a "side wall", and at the same time, he has done many practical and good things for Yulin. This is just an example. At the beginning of his tenure, he was deeply touched by the extreme backwardness caused by the local border congestion, so he presented the article "Opening a School" to the Ministry of Rites, explaining the reasons for running a school: First, Yulin is in a moderate position and has the conditions for running a school. "Twenty or thirty years have passed, and the city is gradually finished, which is suitable for establishing a health school in Gigi Lai"; Second, due to the urgent military needs, "educated people are extremely scarce." Third, students have a source. "Students are born in this city and selected from the handsome children of the East and West Road." After the book was issued by does, Yu Zijun immediately chose the official school site in the west of Yulin City, completed the construction and founded Yulin Health School. In the following Ming and Qing dynasties, there were many schools in Yulin, and education continued to develop. Since then, talented people have come forth in large numbers, with far-reaching influence.
Yulin became the town of Yansui Town, and the urban area gradually narrowed. It has experienced three large-scale expansions: the first time was in the 22nd year of Chenghua (1486), and the original Fort City was expanded northward, with a circumference of about 6 miles. A two-story tower called Jin Woo Tower was built in the north of the city, and the north gate could not be opened under the city. The east gate is called Weining Gate and the west gate is called Guangyu Gate. Today, the area around the temple is the original site of Chengnan City. The urban area of this exhibition is commonly known as the North City. The second time, in the fifth year of Hongzhi (1492), the south of the city expanded to Kaige Building, with a new expansion of about 7 miles. The Kaige Building was changed to the south gate, the added west gate was called Xuanwei Gate (now the Great West Gate), and the east gate was called Zhenwumen (now the Great East Gate). The downtown area on display this time is commonly known as Midtown. /kloc-The third time in Zhengde in 0/0 (15 15), due to the large number of shops and dense population in Nanguan, after the last performance was approved, Cheng Nan was expanded to the Yuyang River today, and the city wall was newly expanded in 0/3. A new south gate, named Zhenyuan Gate, has two gates in the west wall, Longdemen in the north and Xinlemen in the south. The urban area of this exhibition is usually called Cheng Nan. These three expansions are often called "three extensions to Yuyang" in history books, also known as "three extensions to Yucheng".
List the expansion of Yulin ancient city, only to find that there is no north gate! In fact, throughout the Ming Dynasty, in order to prevent the invasion of northern nomads, Yulin City never set up a north gate, but built a tall Zhenbei Building on the wall of the North City for overlooking. Yulin ancient city wall has a history of more than 600 years since its completion. The existing wall of the ancient city is 5500 meters, and 1992 is listed as a provincial key cultural relics protection unit, including the remote gate and urn in the south city, the five gates and urn in the east city and the Yucheng gate in the north city. In the Ming dynasty, after three expansions, the city expanded; From Jiajing 19 (1540) to Wanli 10 (1582), the bricklaying of the whole city wall was completed one after another, and the city wall became taller and thicker. By the thirtieth year of Wanli (1602), the town north building and the turret building will be built in the urban area. At the top of each city gate, there is an "enemy" building, which is a military building facility for soldiers to climb high and look out, shelter from the wind and rain, and store weapons. There are crocks at the east and south gates, and each door has thousands of doors.
Yulin City Wall has always been surrounded by three mountains (Tuoshan, Hongshan and Heishan), and two waters (Yuxi and Yuyang) flow around it. In the Qing Dynasty, it was built many times. Tongzhi for 2 years (1863), due to the destruction of vegetation, quicksand accumulated in some urban areas of the northern city, and the northern city was abandoned, and the city shrank to the south, which roughly became today's scale. Yulin city wall is still magnificent, and it has been built continuously in recent years, which is a witness to a great historical event. If you walk into the ancient city, you can see quaint tile houses and quiet quadrangles in the criss-crossing long streets and short lanes, so that visitors can enjoy the life interest that has been passed down for hundreds of years in surprise.
