1. In the first case, high-ranking officials also hold high-ranking official positions. For example, Sun Chang Wuji, a famous power minister in the early Tang Dynasty, once served as the "proofreading secretary (Zhengyipin)".
2. In the second case, there is no need to master the official title of actual power, which is somewhat similar to today's "honorary position". For example, Du Fu once served as a foreign minister of the Ministry of Supervision, and was later called "Du Gongbu". However, Du Fu never stayed in the Ministry of Industry in his life. At that time, his actual job was to become the staff of Yanwu in our time.
3. The original meaning of proofreading is "taking charge" or "acting as an agent". For example, in the early Tang Dynasty, General Nanya Sixteen Guards often "proofread" the generals of the Northern Asian Imperial Army, such as "proofread General XXX of Yulin"; Or there are military generals who have the administrative duties of "checking schools", such as "so-and-so general checking the history of the Ministry of Industry" and so on, which is actually "concurrently".
Due to the implementation of the military system in the early Tang Dynasty, the court established the Sixteen Guards. The name of Sixteen Guards changed greatly in the early Tang Dynasty. By the early Tang Dynasty, it was generally fixed as left-right guards, left-right guards, left-right guards, left-right guards, left-right guards, left-right guards, left-right guards, left-right guards, left-right guards. Qian Niuwei in the Tang Dynasty was the imperial army, and General Qian Niuwei was the commander of the imperial army.
5. For example, Li Yuanfang's "General Qian Niu Wei" belongs to the second situation. Because he is only a "Niu Qianwei's corps commander (below level 4)", his rank is two levels lower than that of "general (below level 3)", which does not belong to the situation of "low rank with the same title"; Moreover, Li Yuanfang is not in charge of "Qian Niu Wei", does not participate in large-scale court meetings and ceremonies, and just follows Di Renjie to investigate cases everywhere.
Extended data:
1, the name of "Qianniuwei" began in the Tang Dynasty, and the official name was "Zuoyou Qianniuwei". 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.
2. During the Northern Dynasties and the Northern Wei Dynasty, a kind of senior guards appeared. In addition to being responsible for the safety of the emperor, they also held imperial knives. This kind of guardian is "a thousand cows for health". At first, when "a thousand cows for health" appeared, it seemed that there was no special organization to command these military officers. Later, Emperor Xiaoming of the Northern Wei Dynasty took the lead in attacking in the middle period, which probably led to the emergence of "a thousand cows for health".
3. 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".
4. In the Tang Dynasty, there were two kinds of officials: virtual titles and actual rewards. General Qian Niuwei, the proofreader, has a nominal title (equivalent to modern rank) and no actual power, which is equivalent to an honorary position, the same as the vice chairman of modern CPPCC.
In the early Tang Dynasty, the commander of the military region was called a general (only in the army, regardless of politics), and the whole country was divided into fifteen routes. For example, the general manager of Hebei Road March is equivalent to the commander of the modern Beijing Military Region, but not necessarily a general.
5. Di was appointed as the deputy commander-in-chief of the Hebei Road March (the real name was Prince, but it was true). When he arrived in Xuanzong of the Tang Dynasty, he was renamed our time. The whole country was divided into ten sections, and he was in charge of all military and political affairs within his jurisdiction. This change is one of the reasons for the decline of the Tang Dynasty.
Therefore, in the TV series "Detective De Renjie", Li Yuanfang, the "General of a Thousand Cows", is actually equivalent to a modern army general, and is the entourage of the Prime Minister.
