Watching costume TV series, it seems that you can always see the three words of "no battle card", the two sides fight, and one party can suspend it by hanging a free war card on the city wall.
Let's first take a look at the story of the first record in history of the "battle-free card".
It was the "Battle of Jing" during the Ming Dynasty, Zhu Di encountered a person who made him very helpless when attacking Jinan, this person was Tie Xuan, Tie Xuan could not withstand Zhu Di's strong attack for a while, so he hung up the battle exemption card, did not expect that Zhu Di really did not continue to attack, so Tie Xuan let people rush to make Zhu Yuanzhang's tablets overnight, all placed on the city wall, and then took away the free war card, the result was that Zhu Di attacked was not, not attacked, and finally was repelled by Tie Xuan and other reinforcements. However, in the end, Tie Xuan was executed by Zhu Di because he let people use Zhu Yuanzhang's tablet as a shield.
The battle-free card in your eyes is like this!
The ancients generally paid more attention to honesty, so as long as one of the two sides hung up the exemption card, they could stop the war, and then the people in the city could sit back and relax, while the other side could only scold a few words of relief except helplessness, and had to wait until they took the free battle card and then organized the attack. Because the ancients paid attention to etiquette, you must agree with both sides, since you don't want to fight now, then I will wait for you to fight again, although it is only temporary, but this premise must be observed by both sides, then the free battle card is useful.
Is there a free card in reality?
In fact, in the Spring and Autumn period, the two sides of the war are agreed upon, we will fight tomorrow, where and where, and then the next day to fight, but they will not kill them all, it is said that after the Jin state was defeated by the Chu state, many people fled, when the Jin people fled, the car was broken, the Chu people also helped them repair the car, the Jin people also laughed at the Chu people have rich experience in escaping, of course, this is only in the Spring and Autumn period, after the Warring States is not the same, because the ceremony collapse is bad, it can be said that a hundred families are released, all kinds of schemes and routines emerge in an endless stream, Do you think the free card is still useful? Just like Zhuge Liang six out of Qishan, fortunately, Cao Wei has a foundation, if it is relatively weak, hanging a free war card is estimated how to perish do not know, people come from afar, come once to prepare for a few years, you tell me to avoid war, wait a day is a day of grain and grass. Therefore, there will be no such thing as a war-free card, otherwise this thing exists, and there will be no war in the world.
The free card is still useful in special cases
There are also two sides of equal strength, for a long time can not attack, the soldiers on both sides are exhausted, at this time one side to hang up the free battle card is effective, even verbal discussion. There is also a strategy, hang out the battle-free card, that is, it should not be fought, this kind of belongs to the city that is easy to defend and difficult to attack, and the side that attacks the city can only be scolded, a bit and Zhuge Liang sent women clothes to Sima Yi a reason.
