Unity means putting the interests of the team or the collective first and the interests of the individual second. For example, when a school holds a sports meeting, someone needs to make class clothes, class flags, towels, water and other related items needed for the sports meeting. Also need someone to participate in the competition, win glory for the class, and also need cheerleaders to cheer for the students who participate in sports competitions.
In addition, some students may be required to provide "medical" services, for example, someone is injured and needs someone to take care of him or send him to the infirmary. All these require the students in the class to unite to complete, and one student alone can't do it. At this time, unity and cooperation are particularly important.
