Cultural soul, cultural landscape. Library is the cultural soul and landscape of a city. It provides every reader with a harbor of peace of mind and a place to enjoy loneliness. The library is like a lighthouse, which is isolated from the noise and temptation of the outside world and makes people immersed in rare peace. A library is an institution that collects, sorts out and collects books and materials for people to read and refer to. As early as 3000 BC, libraries appeared. Library has the functions of preserving human cultural heritage, developing information resources and participating in social education.
