The Byzantine government attached great importance to the construction of the library because it was the main part of academic research. In the early days of the People's Republic of China, the government allocated special funds to collect and sort out ancient books and set up national libraries in large and medium-sized cities. It was during this period that many works of the ancient Greek era were systematically sorted out. The ideological autocratic policy implemented in Justinian era once destroyed many libraries, among which the books in Alexandria and Athens were the most seriously damaged. However, folk books are still very rich. Proud Romus (1/kloc-0 ~1170), a famous poor poet, widely borrowed folk books, taught himself ancient grammar and rhetoric, and became a knowledgeable poet by studying most works of Aristotle and Plato. Due to the strong support of national policies, church libraries have developed rapidly, and almost all churches and monasteries have set up libraries. These libraries later became important places to train scholars, and they are still inexhaustible treasures of ancient books. During the reign of the Latin Empire, Byzantine education and academic development stagnated. In the battle for feudal territory, western European knights with relatively backward culture intentionally or unintentionally destroyed Byzantine schools and libraries. They burned ancient books to keep warm. The situation is similar to that of the Germans burning wooden boards engraved with Roman laws in Rome in the 4th-5th century. In the political movement of national rejuvenation, Byzantine intellectuals set off an upsurge of reviving Greek culture. Scholars scattered all over Byzantium gathered in the Nicaean Empire, the political center against Latin rule. With the support of the Laskaris Dynasty, they carried out various activities to rescue ancient books and cultural relics, or visited the Balkans and Asia Minor to collect and copy ancient manuscripts, or collated and annotated ancient classics, or set up private schools to impart classical knowledge, organize academic discussions, and preserve books in various ways. These activities laid the foundation for the "cultural revival" during the reign of the Pale Oleg Dynasty. The famous scholar Boulami Dis (1 197 ~ 1269) was the leader of Byzantine culture during the Nicaean Empire. He trained many knowledgeable scholars, including Emperor Theodore, and was widely respected in the cultural circles.

It can be said that the Byzantine cultural and educational activities in the Pareg era were part of the national rejuvenation and self-help movement. At that time, the Byzantine country had declined, the domestic political situation was turbulent, and foreign enemies bullied it, and it was gradually heading for the abyss of extinction. In order to save the nation from peril, the Byzantine intellectuals launched a cultural revival movement on the basis of the Nicaean imperial culture and education, which made the development of Byzantine culture and education enter another glorious period and an unprecedented group of scholars appeared. They actively participated in political and religious affairs, studied ancient Greek literature, history and philosophy, and engaged in education, thus becoming part of the national rejuvenation and self-help movement. Their extensive knowledge of classical philosophy and literature surprised their Italian students. Many of these scholars and their disciples later became the direct promoters of the Italian Renaissance. Until the Byzantine Empire was about to perish, many folk reading groups and academic salons were still active in Constantinople and Thessaloniki, and they often organized discussions on the most famous works of ancient Greek literature, history and philosophy. A few schools still maintain high-level educational activities, and students from all over Europe continue to study here.
