Economic factors are the basic factors for the development of cultural factors. Marx said that "the economic base determines the superstructure", which is not unreasonable. Before the Tang Dynasty, the Three Kingdoms and the Northern and Southern Dynasties were all at war, and the poetry genres were often varied. Despite the unification of the rulers, the overall productivity is still declining under the influence of the war in the north. Although the Sui Dynasty unified the whole country, like the short-lived Qin Dynasty, it only lasted for two generations. The development of culture needs long-term stability. Then, this period will not develop well. Then in the Tang dynasty, the first thing is to pay attention to rest and promote the development of productive forces. A large number of idle land has been developed, and the emergence of a large number of working people has promoted the development of economic level. The great development of productive forces has created a material foundation for the development of culture. The appearance of these economic factors promoted the literati to eulogize that era, thus preparing the material power and ideological source for the forward development of culture.

2. Political stability

The Tang Dynasty was more open in culture than at any time before it. I think this has something to do with the ethnic minorities born in the north in the Tang Dynasty. Although we know something about the culture of the Central Plains, especially the Confucian culture since the Han Dynasty, the rulers of the Tang Dynasty have their own understanding, which can be said to be a heterogeneous culture. It is this heterogeneous way of understanding that enabled the rulers of the Tang Dynasty to implement cultural policies different from those of the previous dynasties. The cultural policy they pursued was cultural understanding and cultural integration, which conformed to the trend of ethnic integration at that time, adapted to the law of cultural development at that time and promoted the development of Tang culture.

3. Cultural prosperity

As mentioned above, economic development and political stability make the development of culture particularly rapid and prosperous. Just like now, culture is diversified. Freedom of speech is still extremely important!
