It means that people who are too kind can't lead troops, people who are too emotional can't achieve great things, people who are too loyal can't manage money, and people who are too kind can't be officials. Therefore, all these require people to overcome their "desires", be rational and respect objective laws. Compassion, attaching importance to feelings, being loyal to others and being kind to others are all very good qualities. With these inner qualities, great things can be achieved.

The words "benevolence and righteousness don't take charge of soldiers" and "benevolence and righteousness don't take charge of money" have their origins, and they come from gracing the literary world.

The original sentence is: benevolence and righteousness do not take charge of soldiers, and benevolence and righteousness do not take charge of money. One person guards it, and ten thousand people can't force it. Nothing people care about, life is arranged by fate. However, there is no specific source of "feelings are not established" and "good officials do not act". This is just a popular saying.

Don't command the soldiers: Cao Song has a poem: "If you don't say it, you will do it." A general's success is achieved by sacrificing thousands of lives. A person who is too kind is not suitable to lead troops to fight. In China, we emphasize the golden mean. It is necessary to make war decisions in wartime and to govern the country with benevolence in peacetime.

As the saying goes: Without rules, there would be no Fiona Fang. Rules and principles are established to manage things well. If a person is too emotional and breaks the rules he has set casually, there is no principle at all. Such people can't achieve great things.

Don't manage money: Jews have a rule in doing business: don't lend money to friends. If you lend money to a friend, once it is time to pay off the debt, the friend will be afraid to see you and avoid you, so that there will be bad blood between the two good friends and they will gradually alienate each other. If you are friends and have difficulties at home, you will help each other appropriately (you can't rely on them to make friends), and you don't need to pay back the money you naturally help, so your feelings will be deeper in the future.

Kindness is not an official: in officialdom, being too kind will be calculated by others. The establishment and implementation of a system will certainly encounter many obstacles. If you are afraid of offending people everywhere, it is impossible for such people to be an official.

In short, all these require people to overcome their "desires", be rational and respect objective laws. Compassion, attaching importance to feelings, being loyal to others and being kind to others are all very good qualities. Only with these inner qualities can we achieve great things, but we must not let these qualities become superficial and vulgar (too much).
