How should students do a good job of safety protection after the opening of colleges and universities in Beijing?

Students should strengthen health monitoring within one week after returning to school. Within 3 days after returning to school (including returning to school after business trip and social practice), all students can only go in and out of the dormitory, pack and take food in the designated canteens (the first floor of Yushu Garden, the first floor of Tingtao Garden, Shuangqing Garden, Rongyuan Garden and Muslim Restaurant), and carry out appropriate personal sports in the outdoor open space. They are not allowed to enter other indoor places, gather or eat. In the meantime, the students' Bauhinia code will be set to Gray code. Within 7 days after returning to school (including returning to school after business trip and social practice), all students must do personal protection, do not gather, do not have dinner, do not go to indoor places unless necessary, minimize contact with others, complete nucleic acid testing according to the requirements of Article 8, and report any abnormal physical symptoms or trips related to the epidemic situation as soon as possible. Students can go to the dormitory leadership office and other places after returning to Beijing for 3 days. After 72 hours in Beijing, check the certification materials (such as bus code, nucleic acid detection location or ticket information), nucleic acid detection results within 48 hours and Beijing Health Treasure, and scan code activation to confirm that the Bauhinia code is changed from gray code to green code. Students who have been in Beijing for less than 7 days need to have 1, 2, 3, 5 and 7 days for five consecutive nucleic acid tests after returning to school; Students who have been in Beijing for 7 days have to do nucleic acid tests twice within 3 days after returning to school. After that, please continue to do normalized nucleic acid detection as required.
