Gorky once said: "Creation depends on wisdom, and the world depends on common sense; there is common sense and no wisdom, which is called mediocrity, and wisdom without common sense is called clumsiness." Wisdom is the most powerful of all forces, the only consciously living force in the world. "Only wise people can create something, and wisdom creates the driving force of culture and knowledge." In the history of our country, the inventions and discoveries of wisdom and creativity, sometimes we will unconsciously lament the wisdom of the ancients.
I believe that everyone has seen in both history books and costume TV series that when the ancient nations were engaged in war, the first thing to attack the city was to attack the city gate. Many people will say that the ancient city gate was made of wood, why didn't everyone burn it, but took a more complicated and troublesome ladder to climb the city wall. In fact, they don't want to, but they don't dare. And here it shows where the wisdom of our ancients lies, so what is the reason?
The city gates are made of special material and are difficult to burn
In fact, the flammability of wood is a truth that everyone understands, and generals and soldiers in ancient times have also thought about such a problem, but there is a big problem in actual operation. There are such examples in the records of the Ming History.
In 1461, Cao Qin rebelled and attacked the Dongzhimen of the Imperial City by burning the city gates. However, when the fire burned, the soldiers guarding the city were very calm, and threw firewood to increase the fire. Eventually the gates were damaged, but the fire was too strong for the rebels to enter the city. In the end, reinforcements were waited for, and finally it ended in failure.
It can be seen from this that the method of burning the city gates is indeed not feasible. On the one hand, it is because the material used to make the city gate is very special. The city gate is the most important protection of a city, of course, everyone must protect the city gate from damage, so even if the use of wood to make the city gate, it is also the use of jujube wood, iron birch wood these materials hard and non-combustible wood.
At the same time, when making the city gate, it will be painted on the surface of the city gate, applied or made a protective film, so that there will be a layer of partition and a certain degree of flame retardancy. And the city gate as the façade of the city will be well decorated, the ancients will add some rivets and iron sheets when making the city gate, and strengthen the city gate to increase the aesthetics.
In summary, burning the city gate by fire is obviously not a good way, so in ancient times, when fighting, it was preferable to use the combination of hitting the city gate and climbing the city wall with a ladder.
The guardian of the moat
In ancient China, whether it was a large city or a small city, or even some villages, a moat would be built. For the whole city, the moat plays a very important role.
It is built around the entire city wall, forming a barrier inside and outside the entire city, which plays an important role in the life of the residents of the city and also plays an important role in defending against foreign enemies.
In ancient times, there were many wars, but the era of cold weapons was not as high-tech as today, so when fighting, attacking the city gate was victory. The construction of the moat and the construction of the city wall served as a natural barrier for enemy attacks.
If you want to use fire to burn down the city gates, the moat can also play an important role. When the enemy uses the method of burning the gates, the water of the moat can be used to extinguish the fire and protect the gates.
Moreover, when designing and building the city gate, this engineering method has been thought of, so it will leave a gap above the city gate, and everyone can get water without going downstairs, directly cite the moat, and pour out the fire of the city gate from top to bottom.
Therefore, in the large and small cities, the moat has become the most important link in the construction of the city, which is very important for the safety of the entire city.
Avoid self-casting netting
We ancients were very wise, and when building a city, we can't only have the city wall and gate, this layer of defensive barrier. After the destruction of the city, it will generally face greater and more dangers.
In ancient times, when building city gates and walls, the most conventional construction methods were generally used to ensure that they would not be damaged due to the influence of external factors. Of course, in the event of war, the city wall and the city gate will also play a certain protective role, but if the enemy is too strong, the city gate will be breached, and if there is no second protective city inside, it will be very easy to be attacked.
Therefore, when attacking the city gate, everyone prefers to use the way of cloud ladder to occupy the city gate and the city wall from above. If you use fire attack, you will really burn the city gate and enter the city from below, so that it is easy to fall into the trap, and the urn city behind the city gate will bring greater danger. Therefore, not using these methods is also to avoid throwing a net and being caught in the other side's urn.
After such a long period of development, many excellent cultures and creations in ancient times have left a lot of splendid heritage for our descendants. After the research of historians, such a design of urn city exists in many cities, especially Nanjing.
After Zhu Yuanzhang fixed the capital nanjing, in order to consolidate his rule and strengthen the protection of Nanjing, 13 gates were built alone, and after these gates were urns, if the city gates were opened, they would break into a bigger trap.
This construction of Nanjing has been preserved for a long time, during the Taiping Heavenly Kingdom, when Zeng Guofan attacked Nanjing, he preferred to dig an underground passage rather than attack the city gate. Therefore, in ancient wars, attacking the city gate was very labor-intensive, and the use of fire attack was not an advisable method.
Therefore, experts will say: "It is not that you don't want to do it, but you don't dare to do it." On the one hand, the fire attack is not easy to succeed, but even after success, there is such a dangerous design as Urn City waiting for you.
With the change of the times and the development of science and technology, hot weapons such as gunpowder and muskets have gradually appeared in wars, and they have played an increasingly important role in war. At this time, it is no longer difficult to attack the city gate and break through the urn city, but we have to admire that the construction of the ancient moat, the design of the city gate, the design of the urn city, and even the design of the entire city are full of wisdom and whimsy.
brief summary:
The culture of the Chinese nation has a long history, and our ancients used their wisdom to create a miracle with one. They have created countless wealth with the only materials in their hands, which are not as good as themselves, but also leave us wealth. Whether it is the four major inventions or various strange books, they have always influenced us and led us to a more civilized and era.
Emerson said, "A reliable sign of wisdom is the ability to find miracles in the ordinary." "It is based on the observation of every little thing in daily life that more wealth can be created.
Whether it is the Mojia School or the handicraft master Lu Ban, their creation comes from life, and their wisdom comes from life. Therefore, today we have to thank the ancients for the many conveniences they have brought us, and we cannot go to mediocrity ourselves. We must be good at observation, extract more information from our daily lives, and create our own wisdom.
