1. There have been famous prosperous times in China's history, such as "the rule of Wenjing" in the Western Han Dynasty, "the rule of Zhenguan" and "the prosperity of Kaiyuan" in the Tang Dynasty, and "the prosperity of Kanggan" in the Qing Dynasty. On the whole, the Tang Dynasty is the most powerful dynasty.

2. In its heyday, the Tang Dynasty made great achievements in culture, politics, economy and diplomacy. It was one of the prosperous times in the history of China and one of the great powers in the world at that time. Silla, Koguryo, Baekje, Bohai and Japan were greatly influenced by the Tang Dynasty in political system and culture.

3. In terms of culture. The culture of the Tang Dynasty was in its heyday, which influenced the culture of the whole world. For example, Tang suit, Tang people and imitation buildings are popular all over the world, and foreigners are also popular with China's fat aesthetic. The culture of the Tang Dynasty attracted waves from all directions. Tang Wenhua is the most famous and influential city in the world today.

4. The military and economy of the Tang Dynasty were also very strong. Otherwise, it will not support the powerful economy of the Tang Dynasty. The economy of the Tang Dynasty was absolutely developed, which can be explained from one aspect: emperors of all dynasties overhauled their tombs. When they see the Ming Tombs or other tombs, they can find huge ground buildings and huge tombs, but only the tombs of the Tang Dynasty were built to repair tombs and transform a mountain into a mausoleum, and only the emperors of the Tang Dynasty. Therefore, it was called the "prosperous Tang Dynasty", and later generations did not reach the level of the Tang Dynasty (except in modern times).

5. After the Anshi Rebellion in the Tang Dynasty, it was badly weakened and gradually embarked on the road of decline, but it was still much better than Song, Yuan and Ming.
