Taiyuan University of Technology has a Central Library (Huyu Campus) and a North Library (Yingxi Campus). You can enter the Central Library (Huyu Campus) at the gate, but you can't read books or magazines. You can go to the self-study place to see how students studying for postgraduate entrance examination or exam review in Polytechnic University study, while the North Library (Yingxi Campus) is newly renovated with new facilities, and students are completely warehouses for borrowing books. However, outsiders are not allowed to come in casually. Even with security doors and guards watching, they are still afraid of losing their books. Students here bring their own cards in and brush them at the door before they can pass, and the name of the cardholder will be displayed at the door. If you want to enter, for nothing else, you have to have a card.
