As for the academy, it was first established by Emperor Xuanzong of the Tang Dynasty, which is equivalent to a traditional educational institution. Then in Xuanzong of the Tang Dynasty, the academies were probably established by wealthy businessmen or scholars themselves. Then the academy was probably built in some remote mountains, and then it was for better study and training talents. Therefore, the earliest academy was built in Luoyang, called Li Zheng Academy. Probably all the talents in it can serve the country, and then the throne of the emperor will be consolidated, and Tang Xuanzong will naturally get many benefits.
? At this time, the most important function of the academy is to collect books. But at the same time, the research institute also serves some other functions, such as the management function of government agencies. That's more than that. Its function is that those scholars can write an article and even give lectures here.
With the development of the times, many functions of the academy are quietly changing. At that time, its function was not only to store some books here and provide poems for some literati, but also to cultivate some talents for the country and then spread some new ideas. So the development of the main era will change the academy.
Oh, to answer the first question, why did Tang Xuanzong set up a college? In my opinion, I think the original intention of Tang Xuanzong in establishing the academy was because he wanted to collect more books, so that more books could be collected in the academy instead of living on the earth. It can be seen that Tang Xuanzong was a book lover. Therefore, this is probably the background of Tang Xuanzong's establishment of the Academy.
