Dry goods (seat grab guide): 1. It is recommended to come to the library early, but not too early. 8 o'clock is the most suitable time. It is strongly recommended that you find a place near the wall, because there are sockets for charging your mobile phone and computer, because you may need them to watch online classes.
If you haven't bought a computer, don't buy a game book. I use a game book. If you don't have a charger or can't find a socket, you know the pain of the game book (endurance anxiety).
3. Lock the seat. At present, general university libraries have the operation of two-dimensional code seat locking, and seats can be reserved in advance. If you don't want to get up early, it's ok to take up space online.
