Interesting answer: The origin of the release is an escort.
Folk tales
Let's start with a folk tale and then tell you a little bit about the historical record associated with it.
It is said that in a certain dynasty, because of a certain battle, some people need to be escorted to another place, and in the process of escorting, it is natural to need to be strictly guarded, each of them with handcuffs, shackles, and a long journey every day.
But everyone should know that people have three emergencies, it is impossible to hold back, so there are some people who will always have this rush when marching and fighting, at the beginning the soldiers did not care, but slowly the soldiers found that if they did not care, it was easy to mutiny, so they had to take care of them, every day fixed time, let them solve the personal hygiene problems.
But there is a premise, we must know that when escorting the enemy in ancient marches and battles, the gloves they wore on their hands could not be undone, so they would tell the soldiers every day that they hoped to unshackle their own handcuffs and then let themselves stink.
And then slowly, such a conversation became more streamlined.
Often it is said to untie the hand, because only by untying the hand can you untie it.
Small historical records
There are two real historical records, the first is the battle and the second is the migration.
I don't need to elaborate too much about the battle, because no one knows whether the battle was real or not, but there is still 80% certainty about migration.
After Zhu Yuanzhang established the Ming Dynasty, he found that the entire Ming Dynasty was almost the same as the previous Yuan Empire Huo Huo, there were many places where there was no one at all, and all of them became a large open space, and Zhu Yuanzhang was forced to carry out forced relocation in order to ensure that his people could be evenly dispersed in any inch of land under the Ming Dynasty, and at the same time, let them actively work, forced to carry out forced relocation.
But everyone knows that everyone is difficult to find in their homeland, and everyone hopes to be able to move on their original land, so when Zhu Yuanzhang forced them to relocate, many ordinary people had a rebellious mood, and in order to prevent them from escaping during the relocation, they all tied their hands.
Later, it slowly continued into the matter of understanding hands.
