Why did the two armies fight each other without cutting history?

There is no such thing as "etiquette", war is a continuation of politics, and the two sides still have to abide by certain rules of the game despite being hostile to each other. Otherwise, the consequences of war are unimaginable. For example, in the US-Iraq war, neither side used nuclear, chemical and biological weapons, otherwise it could trigger a global nuclear war.

Even in ancient times, when there was no mass destruction**, spreading plague to the enemy and poisoning water sources were still regarded as the rules of the game for a ring breaker war, because such behavior not only hit the enemy country, but also endangered the vast number of third countries, and would be devastating by the surrounding countries.

The ancients were very particular about etiquette, from the Spring and Autumn Period onwards, under the persuasion of Confucianism, the great powers began to use Confucianism as a governing doctrine, and the "courtesy" in the Analects can explain the etiquette that the big vassal states believed in at that time. China is a country of etiquette, whether it is war or peace, the Chinese pay great attention to etiquette.

It's a kind of agreement to have a conversation!

If a strong country kills a diplomat from a weak country, it will leave a bad name! It's a gentleman's agreement!

The battlefield is changing, there are no eternal enemies and friends, today's occasional victory or defeat does not mean that it will always be so, to make sometimes it act as a buffer, war is for interests, there is no endless war, only endless interests.

Killing a diplomat will force the enemy country to fight to the death, which will increase the losses in battle.

If you cut it, who would dare to send a letter?

Abide by the rules and keep communicating, break the balance, and intensify the conflict

Legal analysis: The messenger is often not malicious, not aggressive, his purpose is only to convey information, if you kill such a defenseless person, you will be looked down upon, and you will be at a disadvantage at the level of moral discussion.

The two armies are at war, and they don't cut them to make them" ** In the Spring and Autumn Period, Hua Yuan of the Song State went to the Chu army camp as an envoy to negotiate, asking the Chu army to withdraw from the capital of the Song State, and the two countries stopped fighting, while Hua Yuan went to live in the Chu State as a hostage, and this rule gradually evolved into "The two armies are at war, and they are not killed." ”

The reason why the two armies fought each other in ancient times:

The ancients paid attention to etiquette, from the Spring and Autumn period under the lobbying of Confucianism, large countries began to use Confucianism as a governing doctrine, the courtesy in the Analects can explain the etiquette believed in by the big vassal states at that time, even if it is a war with a small country, out of etiquette, the monarch of a large country still needs to send a ceremonial department or even personally receive the other party's envoys, China is a country of etiquette, whether it is war or peace, the Chinese pay attention to etiquette; The envoys of both sides of the war often play an important role, and the two sides play a key role in the war and the envoys, so they often do not cut the envoys; In addition to not beheading the envoys, there are also no prisoners, no medical soldiers, no women, children, the elderly, and people who have no ability to resist, etc., reflecting the civilized and humane side of modern society, and at the same time, it is also the image of breaking the enemy's resistance and establishing a righteous division.
