The conditions of Changchun Library are better than those of provincial libraries. The provincial map is too old, the city map is relatively new, and it has just been renovated. Self-study in both libraries is free, as long as books are not borrowed. But if you want to plug in the power, there is a multifunctional study room on the city map, which seems to be on the fourth floor. You can plug in the power supply and network cable. You can go to 2 yuan once temporarily, 1.5 yuan can apply for a card once. There seems to be only a desk for saving pictures in the study room, and there is no power supply.
