What is history: it is the echo of the past to the future, the reflection of the future on the past. - Hugo
ID card for everyone, is very important existence, if there is no it, we go out, accommodation, find a job, and even buy things are not convenient, but sometimes we inevitably encounter forgot to bring the ID card, or even lost it, but fortunately, with the development of the times, what electronic ID card, face recognition system, can completely help each other identify our identity, very convenient.
So the question is, in the ancient times when science and technology were backward, how should the ancients confirm everyone's identity? In fact, as early as 2,000 years ago in the Warring States period, Shang Martin has invented the "body post", it is a polished smooth bamboo board, which is engraved with the holder's head and place of origin information, issued by the government uniformly, if you do not take the body, you are a black household, will be arrested, this is the prototype of the ID card.
With the development of the times, the ancient ID card has also been continuously improved, what tiger symbol, rabbit symbol, fish symbol, turtle symbol, dragon symbol, have been done over and over again, the information has also changed from a simple head portrait, place of origin, to with name, unit, official position and other information.
Then the "waist card" came into being, because it is often hung on the waist, so it is named "waist card", it is not only the identity card of the ancients, but also a symbol of a person's status. The Ming Dynasty also stipulates that people of different status levels should wear different materials and different shapes of waist cards, and this material, ranging from jade, amber to ivory, is extremely luxurious, so everyone can see someone wearing a gorgeous waist card from a distance, and they can know that the other party is either rich or expensive. With their waist cards, the dignitaries were able to enter and exit the palace at will.
But in this way, if there are people who plot against the emperor, steal, or forge waist cards, is it not easy? First of all, the author can responsibly tell everyone that the waist card can be forged, and it is easy to forge.
When Liu Jin vainly tried to enter the imperial palace and assassinate the emperor, it was discovered, the head fell to the ground, and was raided, and when the family was raided, people turned over more than 500 forged waist plates from his home. And the notorious traitor Yan Song, his family also forged the waist plates of the officials, the military department and other departments, the number of which exceeded 300 pieces. It can be seen that it is not difficult to forge a waist card.
The most ridiculous thing is that there is a story in the "Twenty-Four History", when a beggar accidentally picked up a waist card of the imperial dining room, he dared to take the waist card to the palace, and successfully entered the imperial dining room, a full meal, just like this, the beggar came to the palace every day with the waist card to eat and drink, the day was called a "beauty", until a year later, the guards noticed that he was wrong, and found that the waist plate was picked up by the beggar.
So the question is, it is so easy to forge the waist card, and with the waist card you pick up, you can enter and exit the palace at will, what kind of threat is this to the emperors and princes? But for thousands of years, why haven't you heard of the assassination of entering the palace with a waist card? Don't worry, let's see.
The first reason is that the interior of the palace is layered with levels. In fact, all the waist plates were registered that year, which was easy to forge, but it was also easy to be found. And even if you enter the palace gate with a waist card, there are soldiers patrolling and on duty inside the palace at any time, but whenever they encounter those who enter the palace, they will conduct random inspections, which can be described as "hiding through one door, but not hiding from two doors.".
The second reason is that the waist card authority is really limited. As mentioned above, Yan Song's father and son hid more than 300 waist cards in that year, including officials, military departments and other departments, yes, the waist card of that year, the authority is limited, if you only have the waist card of the official, you can only enter the official department; if you have the waist card of the imperial dining room, you can only enter the imperial dining room, and you cannot get close to the core area where the emperor is located.
In summary, it is the reason why it is difficult to get close to the emperor and assassinate the emperor by having a waist card.
