Strange talk about rules: There are billions of horrors in this dormitory

Strange revival, strange talk about rules descends.
Each country will randomly draw a chosen person to enter the world of ghost stories.
If you clear the customs in the rules of strange talks, your country will get rewards for resisting strange talks.
The first strange story is the dormitory.
[End of the substantial study time every day, welcome back to the dormitory to rest, please read this dormitory rule in advance. 】
[[-]: This apartment is configured as a six-person room. 】
[Two: Your lower berth and the opposite lower berth are tables, and there is no roommate sleeping on the table. 】
[Three: Please lock the door of the dormitory when going out after the lights are off, but it is best not to use the door lock distributed by the school. 】
[Four: Make sure there are always people in the dormitory after dark. If there are not enough or overcrowded people, please identify who is your roommate before turning off the lights. 】
[Five: The bedtime check is before the lights are turned off at 22 o'clock. If you hear the sound of bedtime checks outside the door or window after the lights are turned off on 22, please do not call "arrival" when your name is called. 】
[Six: The bedroom is absolutely safe. 】
