Construction period of Hefei moat

At the end of the Warring States period, around 40 BC, Shouchun had developed into a metropolis on the Huaihe River, and the traffic between Jianghuai and Jianghuai had made new progress, so a new city rose at the southern end of the Feishui and Shishui Waterways. This is Hefei.

In the case of the division of the three countries and the division of the north and the south. After Cao Cao managed Huainan and occupied Shouchun and its vicinity along the Huaihe River, he took Liu Fu as the secretariat of Yangzhou in 200 AD, and built an empty city, Hefei (about one kilometer northwest of He Fei outside the west gate of Shuixi) as the vanguard position of Huainan. As a result, the soldiers and sailors of Wei and Wu all went in and out of Chaohu and Dongguan (now the Yuxi River pass between Wuwei and Hanshan counties) and launched a water attack on land. In 2 15 AD, when Cao Cao marched into Guanzhong, only Zhang Liao, Le Jin, Li Dian and other generals led more than 7,000 people stationed in Hefei, and Sun Quan took the opportunity to lead hundreds of thousands of people to attack the city. In this kind of power disparity emergency, Zhang Liao chose eight hundred "people who dare to talk to" to lead out of the city and went straight to Sun Quan's office to fight in the north of xiaoyaojin. Sun Quan jumped off the bridge and fled to the south of the bridge, only to survive, and then left. This is Wei Jun's famous battle to defend Hefei. In 233 AD, Man Chong, commander-in-chief of Wei State, built a new city at the foot of Jiming Mountain, about 15 km west of the city. This city is the famous Hefei New Town. The ruins of this new city are still clearly visible.

During the Wei and Jin Dynasties, the access from Hefei East to Jianye was also developed. In 250 AD, Wu blocked the earth and water in Tangyi (Liuhe, Jiangsu) and built a mud pond to flood the North Road, which refers to this passage.

During the Eastern Jin and Southern and Northern Dynasties, Hefei was the gateway to the west of Jiankang. In 32 1 a.d., Emperor Jin Yuan took Shangshu Dai Yuan as the general of the west, that is, Wang Dun, a warlord who invaded Huaishang in the north and Jingzhou in the west. In 506 AD, the Northern Wei Dynasty captured Hefei City, and Wei Rui, the secretariat of Liang Yuzhou, flooded the city wall with chemical fertilizer, which greatly defeated the Northern Wei Dynasty. Since then, the ancient city has been abandoned gradually because of its low terrain.

At the beginning of Sui Dynasty, Luzhou was set up in Hefei, as the general manager of Luzhou, and a town was set up to prepare for the felling of Chen. In 589 A.D., he marched into cutting Chen, from Hefei No.1 Road to Hengjiang (southeast ferry of Hexian County) and crossed to quarrying, which was one of the first main forces to enter Jiankang.

Since the Tang and Song Dynasties, the organizational system of Luzhou has remained unchanged. At the beginning of the Tang Dynasty, a new city named "Jindou City" was built on a highland on the south bank of the He Fei River about four kilometers east of the old city, and a section of Hefei River along the north of the city was also called "Jindou River". During the Song Dynasty, the Jin people invaded the south across the border, and Luzhou was the first to bear the brunt, and was harassed by the Jin army many times. 1 169, the southern song dynasty court ordered the renovation of Luzhou city, and learned that Guo Zhen of Luzhou was urged by the imperial edict to expand the city on a large scale, extending the city wall to Hebei, and bringing the Jindou River and the markets on both sides of the river into the city. At the place where the river flows in and out of the city wall, two more sluices were built later. This city wall is called "Douliangcheng". This has formed the scale of Hefei's modern old city.

During the Song-Jin War, Luzhou was an important town to the west of Huaihe River, and patriotic soldiers and civilians in the Southern Song Dynasty often attacked the puppet troops invading the south of Huaihe River under this city. For example, in 1 13 1 year, Wang Heng, the magistrate of Luzhou, led the whole city's soldiers and civilians and smashed the fake Qi army. 1 134, yue Fei and Niu Hao reinforced Luzhou and pursued the nomads from the city. By the end of the Southern Song Dynasty, 1238, the Mongolian general Chahan and his handsome soldiers claimed that 800,000 troops besieged Luzhou. Du Gao, commander-in-chief of the Southern Song Dynasty, led the soldiers and civilians in the city to stick to it, burned the high dam that besieged the city, built a tower in the city to bomb the enemy and ourselves, and then attacked them, and the enemy was defeated. These battles shine with the brilliance of this historic city.

After the Yuan Dynasty unified the whole country, Luzhou Road was set up in Hefei, which belongs to the northern province of Henan Province. In the early Ming Dynasty, it was promoted to Luzhou Prefecture, directly under the jurisdiction of Nanjing. In the Qing Dynasty, it was still Luzhou Prefecture, which belonged to Anhui Province and led Hefei, Lujiang, Shucheng, Wuwei Prefecture, Chaoxian County, four counties and one state. After the Revolution of 1911, Fuzhou was abolished and Hefei County was retained. The county covers an area of more than 6,000 square kilometers, making it the largest county in the province.

The fall of Hefei broke out in War of Resistance against Japanese Aggression in May 1938. The seven-year military occupation has caused serious damage to this ancient city. After the end of War of Resistance against Japanese Aggression, Hefei became a temporary provincial capital.

After the founding of People's Republic of China (PRC), Hefei was formally established. The original Hefei County was divided into Feidong County and Feixi County. Dao 1964 is divided into Shouxian, Dingyuan, Feidong and Feixi counties. Now Changfeng, Feidong and Feixi counties are all under the jurisdiction of Hefei.

Quite simply, the section north of Nanfeihe River flows into Yuhuatang Baohe River south of Chaohu Lake. It should be explained that there was a natural Chongqing armored Luzhou in the Ming Dynasty after the Qing Dynasty, so the Hefei moat at that time should be the most coherent and profound period.
