Shu County, is now Lujiang County, also known as Shucheng County, even the next door of the Qianshan can not sit still, I am where Luzhou Shu is located. In ancient times, Shucheng and Lujiang belonged to Luzhou. Shucheng is closer to Hefei than lujiang. We all know that Zhou Yu and Erqiao's hometown is in Lujiang, Anhui, Zhou Yu is the Lujiang people, so the ancient Lujiang and Shucheng include the current Shucheng County, Lujiang County, Tongcheng, Qianshan and other places. "Zhou Yu zi gongjin, Lujiang Shuren also." This is the introduction of Zhou Yu in the Romance of the Three Kingdoms, but does this "Shu" refer to Lujiang or Shucheng? Over the years, two neighboring brother counties have fought over Zhou Yu's hometown.
Lujiang and Shucheng were originally the same county in the same county in the long history, and everyone was a brother and sister. Longshu County, Lujiang County, and even Luzhou have been mixed up in ancient times, which is really worth saying. Liu Xin "Don't put Longshu County" "Don't put it" means "set up separately". Because the area was too wide and difficult to manage, Liu Xin divided the shudi from north to south, and the north (Shucheng, Lujiang) was still called Shu County, and the south was called Longshu (Tongcheng) County. But I don't know why, history has always understood the word "other" as "renaming", saying that Shu County was renamed "Longshu County".
The Book of Han and Geography reads: "Lujiang County... Twelve counties under its jurisdiction: Shu, Juchao, Longshu, Linhu, Yanlou, Zongyang, Xunyang, Xiang'an, Qian, Anhui, Hulingyi, Songzi" (1) and so on. The Book of Song says: During the Three Kingdoms period, "Jianghuai was a place of war, and those who did not live in each of them were hundreds of miles away." These counties are in Jiangbei and Huainan, and there are no resettled households. (3) During the Three Kingdoms period, Sun Quan of Eastern Wu and Cao Cao of the State of Wei fought in Jianghuai for many years, and Lujiang County was ruthlessly divided. The State of Wei established Lujiang Commandery in present-day Lu'an, and Eastern Wu established Lujiang Commandery in Anhui City (present-day Qianshan). Today's vast area south of Lu'an, east of Qianshan, Hefei, and west of Chaohu Lake was used as a battlefield specifically for fighting. In order to escape the war, some of the people moved to Qianshan and some moved to Lu'an. To put it bluntly, when Sun and Cao were divided, Shu County and Longshu County no longer existed.
After the return of the Three Kingdoms to the Jin Dynasty, Shu and Long Shu gradually recovered. However, Yao Nai said in the "Examination of the History of Hanlujiang County": "Sui Wushu. (4) What does that mean? That is to say, in the Sui Dynasty, Emperor Wen of Sui abolished Shu County and established Lujiang County. The Etymology further states: "The Sui Kai Emperor (Emperor Wen's era name) was initially abolished (Lujiang County), called Lujiang County. (5) The Cihai says more specifically: "At the beginning of the Sui Kai Emperor's reign, he changed the name of Hezhou to Luzhou, with its seat of government in present-day Hefei, with jurisdiction over Hefei, Lu'an, Huoshan, Lujiang, Chao County, Shucheng, and Wuwei Prefecture."
This place of Shucheng, in ancient times, has not only been the seat of Shu County, but also the seat of Lujiang County, but by the time of Emperor Wen of Sui, it was no longer called "Shu County", and it was renamed "Lujiang County", and the county rule was still here, and the area was the same as the original Shu County, equivalent to today's Lujiang and Shucheng counties; but the county rule was moved to Hefei, and the name was also changed to Luzhou.
Shu County, established by Liu Xin, went through the Western Han, Eastern Han, Jin, and Southern and Northern Dynasties, and was not replaced by "Lujiang County" until the Sui Dynasty (the name "Shu County" existed for about 740 years— 60 years after deducting the Three Kingdoms). At that time, Lujiang County included today's Lujiang and Shucheng counties. Therefore, Shu and Lu counties have always been one territory, one whole, and belong to the same relationship
So, when did Lujiang and Shucheng separate?
In 735 AD, the twenty-third year of Tang Kaiyuan, another piece was carved out of Hefei and Lujiang counties to establish Shucheng County. The New Book of Tang and Geographical Records says: "Luzhou administers five counties: Hefei, Shen, Chao, Lujiang, and Shucheng. Shucheng, Kaiyuan twenty-three years analysis of Hefei, Lujiang. ”⑺
From the establishment of Lujiang County around 590 in the Sui Dynasty to the establishment of Shucheng County in the Tang Dynasty in 735, 150 years later, Shucheng and Lujiang were completely separated, which formed a juxtaposed brotherly relationship.
