However, Lao Cao doesn't quite agree that LZ takes the sketchpad to the library to do his homework, which will occupy a seat for no reason, so that readers who are really eager to acquire knowledge can only sit on the floor or occupy the aisle when they can't find a seat. . . .
If you really need to go to the library to borrow materials or study by yourself, please try to copy, take photos, scan or borrow, and try to take your homework or other personal needs home. Leave more resources of the library to readers who are in urgent need.
