First, the Tang Dynasty was the most prosperous dynasty in history. No matter in politics, economy, military affairs or culture, the Tang Dynasty was one of the best. The reason why the Tang Dynasty can have such a high evaluation is that there are many wise kings among its ruling monarchs, such as Emperor Xuanzong, Emperor Taizong and Wu Zetian. These monarchs played a very important role in the emergence and convergence of the prosperous era of Kaiyuan and the rule of Zhenguan, and finally formed the supremacy.
2. Overlooking the spectacular Chang 'an City, its prosperity is from its bird's eye view. The architecture of Chang 'an City in Tang Dynasty was rigorous, followed the traditional thought of China, and was very symmetrical and solemn. Chang 'an covers an area of nearly several hundred square kilometers and was the largest city in the world at that time. The population living in such a site actually exceeded one million, which is enough to prove the superb architectural level of the architects at that time. Chang 'an City is also self-sufficient, because there will be rivers running through Chang 'an and distributed vertically and horizontally. This kind of building in Chang 'an even provides a good template for Japan.
Third, the prosperity of the market economy In the online drama "The Longest Day in Chang 'an", there is a general description and overview of eastern and western cities. In this online drama, we can find that the more lively market at that time was the east-west market, and the east-west market in history was actually more prosperous than that on TV. There is a difference between the two markets. The western market is equivalent to a very large entertainment place. Not only the civilians in the Tang Dynasty shuttled through it, but also many faces from the western regions, so it was very entertaining, and the East Market was closer to the palace where the king lived, so the atmosphere would be more solemn.
