Do you need to shout slogans to everyone after the training of freshmen in Dalian Maritime University? It is said that the backbone will train everyone for one week, and then the instructors will train for another three weeks. Is that so? No, it's the initial training for freshmen by sophomores (maybe not, it's military training for direct instructors)

Then the instructor's formal military training.

The number of backbones is redundant, and not every backbone can be a monitor.

If you are designated as the monitor, you must shout out the password.
