Ironically, what he is best at is what his mercenaries described as "lack of unity, ambition, lack of discipline and disregard for loyalty, which is the performance of Wu Yao's friendship in his youth and cowardice in the face of the enemy". He proposed that "the main foundation of the national army is that the king gives priority to his army", and it is necessary to use laws to assist in the management of the army. With his own national army, the monarch can really hire a group of troops to participate in the war in times of crisis. If they are suspicious, dishonest and dangerous, he will immediately destroy them and rely on his own strength instead of worrying about falling into a helpless situation.
The army was founded to safeguard national interests, such as Winston Churchill's famous saying: "We have no eternal friends or enemies, only eternal interests." Today's military is different from15th century. Military and military-related activities are not only the simplest retreat, but also the construction and struggle in politics, diplomacy, economy, culture and other aspects. It is directly related to national security, national dignity and social development. It also needs military power as the core premise, armed forces assisted by law to achieve unified will and standardized behavior, and formal order and rhythm to promote science and national armed forces to be better.
So sometimes, with the help of the people's strength, it is much easier to let them manage their original land, and the monarch supervisor will fulfill his obligations at an appropriate time to maintain the atmosphere of free life in the city in order to maintain the rule, which is much easier than relying on any other tough means to reform. However, at special times, as Machiavelli described, "If the conquered cities have strong vitality, greater hatred and revenge than those who have been cut, and they cherish the memory of past freedom, they are not calm, but they can't be calm", then cities have to rely on a unified government and a unified policy for mandatory indoctrination management, because letting them continue to use the existing system will easily form a counterattack situation that is not conducive to national stability.
