How big was the territory of the Tang Dynasty?

As we all know, the territory of the Tang Dynasty in our country's middle school textbooks stretches from the Aral Sea in the west, to the North Sea (Lake Baikal, now in Russia) in the north, to Linyi (now Vietnam) in the south, and to the sea in the east. I I was once proud of the fact that there was such a powerful empire in Chinese history, and proud of the achievements of my ancestors. But as I grow older and gain more experience, I become more and more suspicious of this fact. The basis for my suspicion is What? I slowly realized it. I came to it after reading the history of the "Anshi Rebellion". The Tang Dynasty had an army of 470,000, divided into 9 towns and Jiedushi. Among them, Anlu Shan was the governor of three towns, namely Pinglu (today's Chaoyang, Liaoning), Fanyang (today's Beijing), and Hedong (today's southwest of Taiyuan City, Shanxi). *** 150,000 elite soldiers (the total force at the time of Anlushan's rebellion) ). Except for the Jiedushi of Jiannan, who is in the present-day Xikang area (to guard against the Tubo in the west), the remaining six towns are also on the line of the Great Wall. This is strange, why the territory of the Tang Dynasty reached as far as Lake Baikal , but his main troops were distributed along the Great Wall? There are two more details that can further explain the problem. 1: In order to please Tang Xuanzong, An Lushan often tricked ethnic minority leaders into gatherings, and took advantage of them when they were drunk. He cut off his head and asked for merit from Emperor Xuanzong of Tang Dynasty. Tang Xuanzong was always happy to confer meritorious awards on him. This is one. Second: the emperor also appointed An Lushan as the interview and disposal envoy of Hebei Province, specializing in dealing with Xi and Khitan. If you put the above mentioned points together, you can see clearly. The territory of the Tang Dynasty was limited to the south of the Great Wall, and there was no real rule north of the Great Wall. The actual situation is that in a very short period For a period of time, the military front was either limited to Ji Mi. If the Tang Dynasty really controlled the vast northern territory, why did most of his troops line up along the Great Wall? Who was it used to deal with? Why did An Lushan Why did the emperor chop off the head of the leader of the Khitan tribe in Xi tribe to express his merits to the emperor? Instead of punishing him, why did the emperor reward him with merit and promotion? He was also appointed as the Hebei Province envoy to deal with the ethnic minorities in the north. That can only explain. The Tang Dynasty was in a state of hostility with the northern peoples, and the Tang Dynasty was under great military pressure along the Great Wall.

A friend once told me a joke about Koreans. It was said on the historical map of Korea The Yellow River Basin and the Yangtze River Basin in China were included in the Goryeo Dynasty and the Silla Dynasty in Korean history. Only the southwest corner was left to us, the Tang Dynasty. My friend laughed when he saw it and said that Koreans really know how to daydream. But if we If you think calmly, ask yourself. Why aren't we in China so arrogant? A few "experts" who compile textbooks declare with a stroke of their pen that a place that does not belong to our country is part of our country's history. This is the same as Bangzi. Is there a difference in thinking? Is this recognized by other countries in the world? It’s nothing more than a policy of obscuring the people.

Someone told me that the reason why the north of the Great Wall was included in China’s territory was because they were Tang Dynasty The emperor of the Tang Dynasty once canonized them as a vassal state of the Tang Dynasty. Not to mention that this kind of canonization was temporary, and it only happened when the Tang Dynasty was strong and powerful, and it only lasted for a few decades. You must know that after the Anshi Rebellion, it only lasted for a few decades. The Tibetans invaded Chang'an City three times in 2011. At that time, they were not considered vassal states of the Tang Dynasty at all, and the Tang Dynasty did not have the ability to ennoble them. If I just say this, everyone will find it very funny, ridiculous, and unacceptable. I What we are talking about is the relationship between the Northern Song Dynasty and the Liao Dynasty. The Liao Dynasty was the father emperor, and the Northern Song Dynasty was the son emperor. The Northern Song Dynasty accepted the canonization of the Liao Dynasty, and paid an annual tribute of 300,000 taels of silver. If someone proves that the Song Dynasty is a vassal state of the Liao Dynasty, And if the territory of the Song Dynasty is included in the territory of the Liao Dynasty, are you angry or can you accept it? Since you cannot accept the territory of the Song Dynasty being included in the territory of the Liao Dynasty, don't presume to add the vast northern area to the territory of the Tang Dynasty. This will only make you happy. Smile generously. That will only make people from other countries laugh at us, just like we laugh at sticks. The sage said: "Don't do to others what you don't want others to do to you." This is the truth.

That's the difference. Is a country independent or subordinate? It is very simple. It depends on whether the country has independent diplomatic, financial, military, and civil rights. If it has independent rights, it is an independent country. If it does not, it is subordinate or vassal.
