I think this is the tomb of the Han Dynasty, although dangerous, but risks and opportunities coexist, "Jin Shu Lin Biography" recorded such a dialogue between monarchs and ministers: "The emperor asked Lin and said: Han Mausoleum in the matter, He Naidoye Lin said: Han Tianzi ascended the throne for one year and became a mausoleum." One-third of the tribute in the world, one for the temple, one for the guests, and one for the mountain mausoleum. "One-third of the country's revenues are spent on the construction of tombs for emperors, and the amount of wealth buried in the ground is evident.

At the same time, many people also know that those funeral goods are priceless treasures, destined to attract thieves from the day they are laid into the ground.

Therefore, the anti-theft measures for the tombs can be described as racking their brains: setting up suspicious graves, false tombs, and laying confusion arrays; The stone coffin is iron-walled, and strives to be strong; Multi-layered boulders, tightly sealed and blocked; Secretly set up crossbows, poisonous smoke, and ambush fires, causing the tomb robbers to die outside the tomb gate...... Tomb robbery and anti-theft are like a pair of spears and shields.

In view of the surging trend of stealing and excavating ancient tombs in history, the ruling class of successive dynasties has taken various measures to strictly prevent it, and the anti-theft measures of the mausoleums of the past dynasties can be roughly divided into two categories: humanistic means and technical means.

Humanistic means mainly include moral propaganda, legislative prohibition, and guarding tombs.

For example, the Tang Dynasty stipulated that where there was an amnesty decree, among which the ten evil disobedience and the development of graves were not included in the amnesty, there was a special punishment for the crime of making a grave, and the punishment was determined according to the degree of excavation and damage, and the punishment was punished by imprisonment for the lightest, hanged for the heavier, and even for "destroying people's monuments and stone beasts", they were also sentenced to one year in prison.

Anyone who robs and excavates the mausoleum will be punished as the crime of treason, and regardless of whether the first offender is an accomplice, he will be sentenced to the capital punishment of "Ling Chi"; Anyone who steals the sacrificial utensils, curtains, and food utensils of the jade silk animal prison will be beheaded for public display; If you dare to steal trees in the mausoleum area, not only will you be beheaded, but even your family members will be sent to the frontier to fill the army.

In order to strengthen the guarding force of the mausoleum, there is also a special shrine supervision army, responsible for the protection of the mausoleum, divided into various full-time guard units patrol the mountain, patrol army, royal horse supervision army, royal female army, court room watch army, money mountain army and mourning army, etc., in addition, the tombs also have a guard, responsible for the guard task near the mausoleum.

Moral propaganda and legislative prohibition cost a lot, but not much. Guarding tombs is an effective measure, especially against self-employed tomb robbers. However, although the Ming Tombs were heavily guarded, they were still destroyed by the Dashun army and the Qing army.

The technical means mainly include fortified mausoleums, anti-theft mechanisms, curse intimidation, secret burials, suspected graves and fake graves, thick and thin burials, and no ashes.

Solid mausoleum: strengthen the soil, strengthen the tomb, strengthen the coffin, build a mausoleum by the mountain, Emperor Wen of the Han Dynasty is a known as the "thrifty" emperor in history, the history books record that he is the first emperor in Chinese history to "dig a hole according to the mountain" for the hanging coffin, and this "because of the mountain for hiding", the use of the cliff tomb form that does not cover the mound, which is also to a large extent also for the motive of anti-theft.

Historical Records? The Biography of Zhang Shi records that Emperor Wen of the Han Dynasty once inspected Baling, looked around happily and sighed: "You see, if the entire Beishan is carved into a big stone coffin, where can anyone shake it!" It can be seen that the purpose of his advocacy of using the mountain as a mausoleum is to prevent theft and excavation in the future.

After formal archaeological excavations, in addition to the entire tomb being excavated in the cliff, the tomb and the corridor were filled with huge stones to prevent tomb robbers from entering the tomb chamber from the tomb.

Since the Song Dynasty and the Ming Dynasty, there has also been a new method of pouring the tomb with "Sanhe soil", so that the tomb is tightly wrapped by layers of lime glutinous rice pulp, Sanhe soil, etc., which enhances the sealing and anti-theft performance of the tomb, and this method is especially popular in the ordinary bureaucratic and doctor class.

This kind of tomb was poured more than 10 layers from the inside to the outside with triple soil, mud and mortar, gravel, etc., and the tomb robbers spent a lot of effort to chisel through to the seventh layer, and they could no longer hold on, so they had to go away.

In fact, the most powerful thing is the internal anti-theft organs: such as quicksand to protect the tomb, hidden weapon flaps, poison gas, etc., to set up lethal "hidden weapons" in the tomb, which not only serves the purpose of shooting the tomb robbers, but also can kill a hundred people and scare those who have the intention to rob the tomb.

As early as the Spring and Autumn Period and the Warring States Period, in some tombs, there has been a practice of "accumulating stones and accumulating charcoal" in the tombs, accumulating stones to reinforce, accumulating charcoal to prevent moisture, and playing a role in preventing theft.

According to the records of the "Old Han Yi", in the imperial mausoleum of the Han Dynasty, "the four sides are involved, the east stone is outside the square, the sword household is closed first, the night dragon and the Mo evil sword are set up in the household, the crossbow is ambushed, and the fire is ambushed", which are all "organs" used to deal with tomb robbers. In addition, there are many legends about the hidden crossbows, flap mechanisms or poison gas in the tombs of ancient emperors, which are among the ancient anti-theft measures.

In addition to these, there is also a curse and intimidation, in the tomb stone carved anti-theft mantra "all those who dare to send my mound will never be the queen", which is also recorded in many ancient documents in our country, but it did not play a big role.

As a tomb robber, Xu lived a life where he didn't want to do anything tomorrow, and those intimidation curses really had little effect.

The last and most cruel means of preventing theft by the tomb owner is to never suffer from future troubles.

Successive dynasties generally killed tomb craftsmen to stop the leakage of secrets.

Legend has it that when Qin II buried Qin Shi Huang, in order to keep the secret about the tomb, he forcibly closed the tomb door and brutally buried all the craftsmen who participated in the construction of the tomb without waiting for them to come out, so as to prevent future generations from stealing and excavating.

Therefore, whenever the world is in turmoil, the imperial curtain is the object of looting, tomb robbery and anti-theft measures are-for-tat, tomb robbery is rampant, and anti-theft measures are also progressing. The anti-theft measures were slightly new, and the tomb robbers soon had the technology to crack it.

As a result, there is a vicious circle of "one foot high, one foot high", and on the whole, anti-theft measures have always been in a passive and backward state.

And now we have to face the most powerful anti-theft mechanism, I don't know how powerful the mechanism is, but what we have to face in front of us is a long-lost lock-making process called: 'Bagua Meridian Copper Core Lock'.

This extremely precise pure mechanical lock, has now been lost, mainly because the production process is too complicated, although from the security point of view can almost be comparable to the current electronic lock, but because the cost is too high, so from the perspective of efficiency is not worth the loss.

But when you get here, even if the gains outweigh the losses, there is no way, who calls this an endless number of gold, silver, jewelry, and even priceless things.

Since ancient times, there has been a saying that "three hundred and sixty lines, and the line is the champion". And in the evil deeds outside the three hundred and sixty lines - door theft, door theft is divided into two, theft and tomb robbery, theft in this business, there have also been many masters.

The stunts mastered by these masters are mainly "locking" and "pickpocketing".

"Pickpocketing" refers to the skill of stealing, while "locking" is the skill of unlocking without a key, and lockpicking and pickpocketing can even be said to be an art.

Taking "pickpocketing" as an example, in addition to mastering many arduous basic skills, it is necessary not only to be careful, bold, clear-eyed, and quick-handed, but more importantly, to skillfully divert the attention of others.

Becoming a pickpocketing master is not an easy task, and it does require a series of arduous training.

There are three levels of finger strength: "broken charcoal", "broken chestnut", and "broken stone", that is, with the strength of the three fingers of the index, middle finger and ring finger, you must crush nuts such as charcoal, walnuts, and even stones.

After these three levels, it is necessary to practice accuracy: "hanging bell", that is, hanging an extremely smooth round stone or soap in the air, and hanging a copper bell on each side, to practice until the round stone is quickly removed and the bell does not ring.

The distance of the bell gradually gets closer as the skill progresses, until it is as close as two fingers plus cobblestone. If you can pinch an extremely smooth object out of boiling water with only three fingers in a very short period of time, and your hands are not burned, you will be considered to have practiced.

However, all of the above training is so-called "death" training, because pickpockets are facing people who are constantly moving, feeling and alert in real theft, so the requirements for truly perfect theft are higher.

The highest level of training in "pickpocketing" is carried out with a wooden figure. The wooden man's whole body joints are the same as those of a living person, the wooden man hangs in the air, wears the same clothes as ordinary people, and a copper bell is tied to his body, and the pickpocket has to reach out to take out the items in the pockets of the wooden man's clothes, and the bell does not make a sound because of the shaking, which reaches the realm of the so-called "one bell".

The real master should start from the "one bell", and the highest can be practiced to the "seventy-two bell", that is to say, tie seventy-two copper bells to the wooden man, steal things and the bell does not ring. This kind of miraculous skill, for "pickpocketing", has really reached the realm of perfection.

According to legend, only in the Qianlong period of the former Qing Dynasty, Jia San, the big dragon head of Hangzhou pickpockets, "thief", once practiced to seventy-two bells. Even the famous thief "Swallow Li San" in Beijing and Tianjin at the end of the Qing Dynasty and the beginning of the Republic of China is rumored to have only practiced 48 bells in "pickpocketing".

As for the "locking" training, although it is equally arduous, it does not have so many names as "picking". According to the number of lock pillars in the lock cylinder, with special training tools, and then with the matching practice method, starting from "one column", the highest can be practiced to "twenty-four columns", to this realm, there is nothing that ordinary locks can not open.

Since the lock was invented, it has been widely used, people use it to lock their finances, to prevent people with ulterior motives from stealing, and then with the continuous progress and development of human technology, the style of the lock has begun to become strange, and even now, many combination locks, magnetic locks, etc. are more trusted by people.

But as the saying goes, there is a policy, there are countermeasures, those clever thieves, will not be stumped by this lock, for many experienced thieves, unlocking is as simple as eating, but today we are talking about this lock, it is estimated that no matter how powerful the thief is, there is no way.
