Open the door. The reason why Taishan District Library opened in the Mid-Autumn Festival is not only a supplement to the general municipal libraries, but also a deep excavation of the cultural wealth of university libraries. The enjoyment of knowledge will create more cultural dividends, and universities and society will benefit from the opening of libraries. The opening of the Mid-Autumn Festival holiday also allows students who are far away from home to go home and continue to study and read in the library during the holiday, increasing their wisdom and enriching their life experiences.
