The upper soldiers cut down the plot, the second cut the exchange, the second cut the troops, and the lower attacked the city; the method of siege was a last resort.
Sun Wu was a great military figure in Chinese history, known as the "Saint of Soldiers", and later generations honored him as "Sun Tzu", and he wrote the book "Sun Tzu's Art of War", which provided the basic ideas and strategic guidelines for future generations of soldiers and made indelible contributions to China's military history.
"Sun Tzu's Art of War" can not only be applied to the military, it is also adapted to various fields, from military warfare to daily life, and the art of war can be used everywhere!
Those who are familiar with military books can be successful in all walks of life. The world's great avenue is inseparable from its origin, its roots are the same, as long as you grasp the essence of things, do anything is handy, which is why some people can succeed no matter what they do.
Sun Tzu summed up a lot of military ideas for future generations, among which everyone is most familiar with the four ways to fight a war - "the upper soldiers cut the plot, the second cut the friendship, the second cut the soldiers, and the next attack on the city."
Sun Tzu believed that the highest realm of fighting a war with troops is to use strategy to achieve victory, followed by diplomacy to achieve victory, these two ways of using soldiers are the most brilliant, and soldiers can achieve victory without bloodshed, which can be described as the essence of the way of using soldiers.
The above two are brain-moving, and the following two are hands-on. The third is to attack the enemy by force and achieve victory, and finally the soldiers attack the city and climb the city tower to attack the enemy.
In ancient times, these four ways of using soldiers, Sun Tzu believed that the siege was the "next strategy", the first siege of the city suffered heavy losses, the probability of victory in the second siege was very small, many people chose to siege the city, but many soldiers died, and the city was not captured, which can be described as more than worth the loss.
In order to enhance the defensive performance of the city, the ancients generally adopted two methods, the first increased the height and thickness of the city wall, which increased the safety factor, and the second ancients built a moat outside the city.
In film and television dramas, we often see that there is a long river outside the city, which is not for the people to play and fish, but to resist the enemy and protect the city.
Adding a river between the land and the city is equivalent to adding a security barrier, using the river to resist the enemy and causing the enemy to cause losses, so that they will greatly reduce their sharpness when attacking the city, and the probability of the city being attacked will be reduced.
One more barrier, one more security, fighting is not a joke, you have to do everything you can to protect your own safety. The most famous of the moats is the Xiangyang Moat, which has an average width of more than 180 meters and the widest place is 250 meters, which is known as "the first city in China!" ”
It was with such a wide moat that Xiangyang resisted the attacks of the Mongol Iron Horse again and again! If there is no moat, the Mongolian Iron Horse will soon be able to break through Xiangyang!
