Argument:

Both of them are officially employed by the state, and Luda has a higher official position. Ruda's Tijua

According to the seventh record of "History of Song Dynasty Official Records": During the Chongning period of Emperor Huizong of the Song Dynasty (1102-1106), "Tiju soldiers and horses and Tiju soldiers and armor were restored. He is also responsible for guarding the army, supervising the arrest of thieves, and clearing the territory."

It is equivalent to the chief officer of today's reserve force. Manage the training, weapons and equipment of local reserve forces, and also be responsible for arresting bandits within the territory. (Song's field troops were the Forbidden Army and were not under the control of local governors.) Lin Chong's 800,000 Forbidden Army instructors

is the collective name for the training system of the Forbidden Army in the Northern Song Dynasty. Those who can enter the coaching system must go through strict selection, and their personal professional skills must be absolutely excellent. However, the overall level of the training system is low, and they do not have the power to command troops. They are professional and technical non-commissioned officers, similar to the "mixed martial arts technical instructors of the Chinese People's Liberation Army Hong Kong Garrison".

The "800,000 Forbidden Army Instructors" refers to the coaches in the regular army of the Northern Song Dynasty, the Forbidden Army, who specialize in training soldiers in martial arts. Their immediate boss is Coach Du.

During the reign of Emperor Shenzong of the Song Dynasty, the military personnel in charge of training included: patrol envoys, capital instructors, and instructors.

Pouring envoys are military officers, because envoys are low-level military attachés of the eighth or ninth grade, and can be given various names before "envoy". A military officer with a lower rank than an envoy is considered a military officer without merit. The ninth-grade military attache was similar to today's company-level cadres.

Instruct the five commanders of the crossbowmen, the ten commanders of the archers, and the five commanders of the spearmen and swordsmen. Each of them chooses one person who is highly skilled in martial arts to play the role." Another proof is that in the fourth year of Yuanfeng, "the commanders of all the armies wanted to implement the warehouse method in parallel. ", "Cangfa" is Song Shenzong's salary reform measure for the civil servant class. It can be seen that even the commanders of the city who are higher than the commanders will not surpass the military officials.

The 80th Chapter of Water Margin reads——

“…Follow two generals to help Captain Gao kill the bandits. Who are these two generals? One is The 800,000-strong Forbidden Army is the commander-in-chief, and the official is accompanied by the commander of the left Yiwei pro-army, escorting general Qiu Yue; the other is the deputy instructor of the 800,000-strong Forbidden Army, the official is accompanied by the commander-in-chief of the right Yiwei pro-army, and the chariot and cavalry general Zhou Ang."

The instructor first appeared in the army of the Song Dynasty due to Fan Zhongyan's order, "Each commander selects twenty-five young and brave men, and first teaches them how to use bows, crossbows and short soldiers, and then waits for them to master their skills. Then make up for the instructor, and each person is assigned to teach ten people, and they teach each other in order." This means that the soldiers are selected in a ratio of 10 to 20:1 as instructors to teach martial arts. However, at this time it was only a temporary military training position and there was no formal establishment.

At the time of Emperor Shenzong of the Song Dynasty, there were gradually full-time instructors, such as——

“The Kaifeng Prefecture, Jingdong, and West generals will send troops, and one person from every ten people will be sent there. "Instructors learn horse shooting" - this is to select soldiers at a ratio of 10:1, and then gather to receive instructor training;

The eight hundred thousand refers to the total number of soldiers in the Northern Song Dynasty, not the number of students of the instructors. There are various coaches in the Forbidden Army of the Northern Song Dynasty who train soldiers' martial arts. Some of them specialize in training soldiers' guns and clubs, and their coaches are called Forbidden Army gun and club coaches. Some comprehensive martial arts coaches, such as Lin Chong, are called For coaches.

Although coaches are also officially officers in the Forbidden Army, they belong to the low-level non-commissioned officer class. There are many Custodes coaches.
