Why use traditional Chinese characters? This is not only because traditional Chinese characters conform to the beauty of visual architecture and make people look more comfortable, but also because traditional Chinese characters are the result of screening ideographic symbols in ancient China for thousands of years. They are the perfect combination of ideograms and pictographs, full of codes of Chinese culture, and can transmit culture through words, which conforms to the identity of the library as a cultural and educational institution specializing in collecting, sorting, preserving and disseminating documents and providing them for use.
