The name of "Petunia tail" began in the Tang Dynasty, and its official name is "Left and Right Petunia tail". The "Left and Right Thousand Cow Guards" in Tang Dynasty were two of the "Sixteen Guards" in Nanya in Tang Dynasty. They are not in charge of the government soldiers, but are responsible for "staying with the imperial knife" and are the personal bodyguards of the emperor's inner circle. After the late Tang Dynasty, with the disintegration of the "government soldier system" and the decline of "Nanya Sixteen Guards", "Zuoyou Qianniuwei" gradually became an empty name and a part of the virtual title. The Five Dynasties, Song Dynasty, Liao Dynasty and Jin Dynasty are all the same.
Zhuangzi, the Master of Health Care, said: [Kenting] understands Qianniu, but if the blade is newly developed, there is a kind of self-defense imperial knife that emperors carry with them, which is called Qianniu Knife. Its name is Zhuangzi, which means "Sharp can kill a thousand cows". The record of the appearance of "Thousand Knives" can be seen earlier in the Liu and Song Dynasties in the Southern Dynasties. Xiao Zixian (his grandson, about 489-537 AD) wrote the Book of the Southern Qi Dynasty: "Yufu (Yang Yufu) conspired with his party member Chen and other 25 people to kill King Cangwu (meaning" post-emperor "in the Southern Song Dynasty) at the felt house." It's about a famous court coup: In the middle of the night of July 7, the fifth year of the Southern Song Dynasty and Yuan Dynasty (AD 477), Yang Yufu and Yang Wannian sneaked into Renshou Hall and killed the emperor with their magic knives while Liu Yu was asleep. When Niu Qian was preparing for the Northern Dynasties and the Northern Wei Dynasty, there appeared a kind of senior security attache, who was not only responsible for the safety of the emperor, but also held the imperial knife "Niu Qian Dao". This kind of guard attache is "the corpse prepared by Niu Qian before his death". When Niu Qian Wei Gang appeared, it seemed that there was no special organization to lead these military attaché s. Later, Emperor Xiaoming of the Northern Wei Dynasty took the lead in the middle period, which was probably to lead "a thousand oxen should provide for themselves". Later, the names of the institutions that commanded "Thousands of Cows Preparing for War" changed constantly. In the fifth year of Tang Gaozong's Xianqing (AD 660), it was called "Left and Right Thousand Cows House", and in the first year of Tang Zhongzong's Shenlong (AD 705), it was changed to "Left and Right Thousand Cows Guards". From this point of view, "Qianniuwei" was named after commanding the imperial military attache "Qianniubei".
According to the Six Classics of the Tang Dynasty, the Book of the Old Tang Dynasty and the General Classics, it can be seen that in Zhenguan, (the left and right houses are the body) are reduced to the left and right houses; After five years of celebration, Niu Qian's home was established. In the second year of Longshuo, he changed the government to Wei. In the first year of Shenlong, it was changed to Qianniuwei. After the prosperous Tang Dynasty, the "officer system" gradually disintegrated, the power center gradually shifted from "Nanya" to "Beisi", and "Nanya Sixteen Guards" gradually declined, becoming a phantom, and "Qianniuwei" was no exception.
During the Zhenguan period of the Tang Dynasty, he returned to the left and right, leading the government. After five years of celebration, Niu Qian Building was established. In the second year of Longshuo, Niu Qianfu changed to serve Vision Wei. In the first year of Shenlong, it was changed to Qianniuwei. There are about a thousand cattle guards, one general each (the statements of the Six Codes of the Tang Dynasty and the General Code are credible), from the doctrinal point of view; There are two corps commanders each, both of whom are below level 4. Two years of Shenlong (generally speaking; Tang Yaohui said it was "Kaya Hioki, the Year of the Loong, February 19th"). They each had a general, and they were all the best. Thousands of cows are prepared for each 12 people. Xianheng first recovered. Hanging arch for two years, and changed to Feng Yu. Restoration of the first year of Shenlong); About ready 12 people; Prepare one hundred people; The main battlefield is the One Happy and Fifty people. (The Tang Dynasty changed Qianniu to say that Qianniu was prepared for the body, and it was prepared for the main battle from the beginning. ) for the official: each long history is one, from six products; A clerk joined the army when he was in 8th grade; Cao Can military products each one, is eight products; Cao Can military products each one, is eight products; Duties: The left and right guards are generals, in charge of the palace guards and the ceremonial ceremonies in the imperial palace, the viceroy judges guard, the viceroy judges guard and worship the guards, and take care of the affairs of the generals and Cao Cao. About a thousand cows, armed with imperial knives, guards. They are all supplemented by beautiful young children in Yin Gao, embroidered with flowers and dressed in green clothes, which is a good choice for the nobles to start their careers. Get ready, hold your bow and arrow, and stay in the province. Prepare yourself and take care of the waiter. There are thousands of oxen, left and right with bows and arrows to stay and defend, and the main battle is the garrison service equipment. On the day of the reception, he was led to the temples on the left and right sides, and the attendants were listed on the left and right sides of the throne. If you shoot at the palace, the general and the general will lead them to follow. Where did you get a thousand cows to prepare for the exam, prepare for the exam, give classes to cows, and be promoted or demoted? The system is the same as that of Beijing officials. Those who take a thousand oxen as the body, prepare the left and right, and worship in the temple with imperial knives are led by generals and generals, assisted by corps commanders. Anyone who serves, straddles, talks with people, leans over, or speaks to subordinates is forbidden to shake his head and raise his hand. If there is a complaint, if the general manager bears the heavy responsibility of delivering the message and doesn't hear it, the commander will announce it. The palm with a long history judges the affairs of Cao officials. The clerk joined the army and sent it. He checked it and lost it. I'm left-back and right-back. A soldier Cao, a military attache, and a thousand cows prepare their bodies, their books, their honors, examinations, assumptions and salaries. Cao Cao commanded the battle. There are 2 19 things used to defend against war, and 300 things used to feather equipment, which are divided into thousands of cattle. On that day, in addition to holding a knife and arrow, he also prepared a bow and arrow for accommodation. Every month in the main battle, it is commensurate with its status. If you follow the line, you will also ride Coss. I'm with the left and right guards.
