Why should the order of the speech contest be decided by drawing lots?

Be fair.

There is no absoluteness in drawing lots, and the results are unpredictable, which can greatly eliminate cheating.

Speech contest is an effective form of students' self-education. Determine the theme of the speech according to the students' reality. Formulate the detailed rules of the speech contest and hold the speech contest at multiple levels. The students' speeches are full of passion and rich in content.
