The emperors of the Three Kingdoms usually call me, and call me the emperor if I am more lonely.
One of the thirteen secretariat departments of Han Dynasty in ancient Kyushu; Sui and Tang dynasties were the military center, transportation center and commercial metropolis in the north. According to Li Zhou Zhifang, the Northeast is called Youzhou. Its scope is as big as that of northern Hebei and Liaoning. Pingyin, word, hometown Youzhou, strict name. During the Warring States Period, Yan and other six countries merged into the Seven Chivalrous Men. Qin Shihuang destroyed Yan and set up Yuyang, Shanggu, Youbeiping, Liaoxi and Liaodong counties in Yan State. Emperor Gaozu set up Zhuojun in Shanggu; In addition, Yan was founded. Emperor Wu of the Han Dynasty set up the secretariat department of Youzhou, stabbing all counties and countries in Yan Di. Emperor Wu of the Han Dynasty opened up territory and set up Xuantu, Le Lang and other counties, which also belonged to Youzhou. In the Eastern Han Dynasty, it governed counties, eleven countries and ninety counties. Youzhouzhi is located in Jixian County, where it is located, so it is located near Guang 'anmen, southwest of Daxing County, Beijing. Its jurisdiction is equivalent to Beijing, northern Hebei, southern Liaoning and northwestern Korea. After Wei and Jin Dynasties, the jurisdiction of Youzhou gradually narrowed, and the Northern Wei Dynasty only led Yan, Fanyang and Yuyang counties. At the beginning of Yang Di's great cause, the state was set as the county, so it was changed to Zhuo Jun County. In the first year of Wude in Tang Dynasty (6 18), it was re-established as Youzhou, in the first year of Tianbao (742) it was changed to Fanyang County, and in the first year of Gan Yuan (758) it was also Youzhou. The area governs Jixian County. In addition, Fanyang County, which belongs to Youzhou or Fanyang County, was ruled by Zhuozhou after four years of Dali (769), so it is different from this.
Youzhou was originally a land transportation hub at the northern end of Hebei Plain. In the fourth year of Sui Daye (608), Yongji Canal was opened, leading Qinshui to the Yellow River in Nantong and Zhuo Jun in the north. In seven years, Yang Di Yang Guang took a dragon boat from Jiangdu (now Yangzhou, Jiangsu) to Zhuo Jun via Yongji Canal and the Yellow River. In the same year, migrant workers south of Jianghuai transported rice from Liyang (southeast of Xunxian County, Henan Province) and Luokou (northeast of Gongxian County, Henan Province) to Zhuo Jun County, "more than a thousand miles". Due to the excavation of Yongji Canal, Zhuojun at the end of the canal became the center of land and water transportation in the north.
During the Sui and Tang Dynasties, the military position of Youzhou was very prominent. Yang Di built Lin Shuo Palace as his palace in Zhuo Jun. Seven years after the great cause, he sent troops to North Korea three times, all based in Zhuo Jun, and assembled military forces, weapons and grain reserves. In the 18th year of Tang Zhenguan (644), he sent troops to Korea, which was divided into land and water, and the land was also based in Youzhou. In the mid-Tang Dynasty, all ethnic groups in Northeast China were powerful. In the second year of birth (7 13), Youzhou was appointed as our envoy to control Xi, Qidan and other ethnic groups. In the first year of Tianbao, it was changed to john young, our ambassador, with more than 90,000 troops, accounting for about one-fifth of the ambassadors of the ten countries. At the end of Tianbao, An Lushan was appointed as three ambassadors, namely john young, Pinglu (ruling Liucheng County, now Chaoyang, Liaoning Province), Hedong (ruling Taiyuan House, now Jinyuan Town, southwest of Taiyuan, Shanxi Province) and Hebei Road. That is, taking john young as the basic point, he sent his troops against the Tang Dynasty and set off an Anshi rebellion. In the second year of Gan Yuan (759), Shi Siming was Emperor Yan and john young was Yanjing. In the first year of Guangde (763), john young was changed to Youzhou, and Li Huaixian, a subordinate of Shi Chaoyi, was named Youzhou. At that time, Pinglu was no longer in the northern tribes, and Pingzhou (now Lulong, Hebei Province) was retained. In Pingzhou, there is a Lulong army, and the Youzhou ambassador also leads the Lulong ambassador. Then it is called Youzhou, or Youzhou Lulong, or just Lulong. Youzhou is one of the three towns in Hebei Province that did not accept the orders of the DPRK for a long time after the Anshi Rebellion. It was not until (9 13) December that the Five Dynasties were destroyed by Jin Wang Li, and the regime lasted for 150 years. In the first year of Tianfu (936), Shi Jingtang in the latter Jin Dynasty ceded the Khitan with sixteen states in Ji You, and the following year, Khitan took Youzhou as Nanjing. According to the inscription on the stone sutra of Yunju Temple in Fangshan, before the Anshi Rebellion, there were white rice shops, meat shops, oil shops, five-cooked shops, fruit shops, charcoal shops, pig iron shops, grinding shops and silk shops in Youzhou, which were organizations operating similar industries at that time, showing the prosperity of commerce and handicrafts in Youzhou at that time.
