Poetry reading, sign language, essays and chorus, how to work overtime to host cohesion?

There are two ways to increase cohesion, one is simple lyricism, and the other is combining the program content. The second method is preferable because it is closely related to the program and easy to deduct the program name. Cohesion can be refined and sublimated from the program. If the content of the program is the chorus "The Story of Spring", then the cohesion can be: a great man played the notes of an era, and an era wrote a magnificent picture. The spring of reform, the spring of the motherland, let's listen together: the story of spring. This naturally leads to the program. And so on.
