Not only in the Tang Dynasty, but also throughout the ages, China's professional level has been in a downward trend, and its level has plummeted. During the Qin and Han dynasties, there were hundreds of thousands of soldiers in a war, but in later generations, the number of soldiers became less and less. For example, in the Ming and Qing Dynasties, there were only a few hundred thousand people in large-scale wars. Because centralization is more and more consolidated and developed, the size of the army is getting smaller and smaller. Even though the people's level is getting better and better and the population is increasing faster and faster, the number of conscripts is greatly reduced or even dispersed.

As early as the Qin and Han Dynasties, the population of China was only 20 million, but at that time, there was no choice but to compulsory conscription. The people had a hard life, the grain output was low, and eating was a problem. Therefore, a large number of teenagers are willing to join the army to get paid, and during the promotion period, there are many wars, all right? Heroes in troubled times? For ordinary people, this is not only an opportunity, but also a challenge. Everyone wants to get ahead, so every war has 400,000 to 500,000 to 670,000 people. By the time of the Tang Dynasty, it was prosperous, prosperous and peaceful, and most people could basically solve the problem of food and clothing. In such a peaceful era, wars rarely occur, so it is difficult for the god of war to come down and the people are in dire straits.

Of course, there were many God of War in the pre-Qin period, which is undeniable and has a certain exaggerated effect. Maybe it's just a general with strong military ability. After fighting in the front, he sent it back to Korea. Due to the lag of the news, historians supplemented it, and then it became various legends and secrets circulated among the people, so the name of God of War was passed down to later generations, and God of War was once the supreme pursuit of generals in previous dynasties.

With the continuous growth of the central group, even in the Ming and Qing Dynasties, it reached the peak of centralization, and history was often fabricated and rewritten by later generations. There will be some outstanding generals in the later generations. Maybe they have the appearance of God of War, but they also know that once they are successful, Han Xin is the best example. After all, it is not orthodox, even if the power is great, it will be criticized by future generations, so it can only be low-key.
