It is generally better to avoid confrontation. Let's see if we can find an empty seat. If everyone is occupied, choose a seat that looks unoccupied (grab a broken book and take something). Go to the empty seat, put several people's books next to each other, and then choose your own seat. When someone else comes, just say you don't see anyone occupying it. After all, there are administrators who will clear their seats. These people occupy seats like this, which shows that they don't come to the library often and may not be familiar with the management and situation of the library. It is very likely that there will be a great conflict. There is no need to move the seat of Xueba, who is the owner of the library.
