There are generally five interfaces in each dormitory of the Forestry Department, and there is a campus network interface behind each desk, which can be directly connected with a network cable. However, if you want to go to the library and open one of the two seats that enter the door, there are two interfaces below, and you can connect to the telecommunications network by plugging in a telephone line, but if you want to buy a cat, both networks can be used at the same time. Our dormitory has been used.
