I saw this question by chance and answered a few words casually. First of all, the ancient people were at least not as mindless as those who make movies now. In front of the ancient city gate, there was a urn city. The urn city was equivalent to a small city. It was set outside the main city gate to protect the main city gate. If the main city gate is open on the front, the city gates of Wengcheng are open on both sides, and there is no front gate, so there is no way to attack. Second, in front of the city gate, there are also fortifications such as the Sheep and Horse Wall, which play a protective role. Third, above and on both sides of the city gate, the defender will concentrate all kinds of weapons to protect the city gate, because the city gate and the city corner are the most vulnerable positions. Fourth, in ancient times, whether it was a cannon with gunpowder or a counterweight catapult that fired stone bullets, the accuracy was relatively low and the rate of fire was slow, and it was difficult to directly hit the city gate. Fifth, in addition to a thick wooden gate nailed with large copper nails, ancient city gates also had a mysterious gate, a Qianjin gate, etc. Even if the gate was broken, the gate was immediately lowered or closed. Sixth, the city gates are generally not the same, and most of the ancient city towers I have seen have two front and rear gates. Seventh, even if all the city gates are shattered, or even the towers are blasted down, and the city walls are blasted, there are still many ways to be stationed as temporary fortifications, which can still serve as a barrier for defense. For example, there is a kind of equipment called platoon wood, which is specially used to defend against shelling. Its function is similar to modern reactive armor. It is made of wood and blocked in front of the wall or city gate. The attacker sets fire or shelling, and hits the platoon wood first. , Immediately discard it after damage, immediately replace it with another piece, make up for it as it breaks, manufacturing is very simple, materials are available everywhere, as long as you are fully prepared, you can continue to replace it like this, and the attacker will never be able to hit the main target. Finally, even if the city gate is breached, the defending army can use equipment such as knife carts or heavy fire oil carts to block the city gate hole, and the attacker will still be unable to pass. The main features of film and television are that they are easy to shoot, good-looking, and are far from the actual combat. Also, due to the limitations of props and funding, there is very little restoration of the actual situation. Everyone should have a correct understanding. Don’t shoot because of modern people. If you don’t have a brain, you think ancient people are stupid. Digression: The ancestors of the Chinese have established a regime spanning two continents, 20-30 million square kilometers, conquered and assimilated, I don’t know how many tribes, but it’s not all based on Confucian classics, all kinds of high-tech weapons and equipment are direct. Show the power. One more sentence: China is a Chinese China, not to mention that China has always been a multi-ethnic and multi-religious country. Even the Han nationality itself is the result of multi-ethnic integration. At least the descendants of Yan and Huang, the Yellow River Basin and the Yangtze River Basin cannot be the same. Tribal. In addition, the Tang dynasty took down Goguryeo, and the number of households in the Tang dynasty increased by almost one-fifth. In other words, one-fifth of the Tang people were immigrants from Goguryeo. There are Russians in China, and even tens of thousands of people from Italy immigrated to Xinjiang during the Han Dynasty. So they are willing to be Chinese, don’t you want them? We are not united for the sake of unity. Our country is originally tolerant, confident, and absorbing. The four ancient civilizations, only our civilization has not been cut off. This is by no means accidental, but our nation’s continuous struggle and cruelty The result of surviving the competition in the world. If Lao Mei is willing to join China and become a special administrative region of China, I think it can be accepted. We are not afraid of trials. It depends on whether we assimilate them or they assimilate us. We don’t need to be narrow-minded about the regimes and peoples that existed on our land hundreds of years ago. The Vietnamese say that the places where there are kapok trees are all in Vietnam, yes, yes, Vietnam, isn’t it the Annan House of ancient China? The places where there are kapok trees are from Vietnam, and Vietnam is from China. The Koreans say that in the history of Northeast China is Goguryeo, and even Shandong. That’s right, Goguryeo belongs to China for 1,400 years. China’s own administrative region can be assigned to any province. It’s okay to restore Dodder County. We don’t care about accepting South Korea as a province of China. After all, it’s a big deal, isn’t it? So, regardless of the Han nationality or which nationality, we are all a family, we are all Chinese. It is nothing more than the difference between your family living in a row of No. 1 and my family living in a row of No. 4. You like spicy chili and I like soup. There is no need to take the rest seriously.
