First of all, the hearing can ensure the correct exercise of the people's court's judicial power. Through trial, judges objectively identify the facts of civil cases, comprehensively examine evidence, distinguish right from wrong, and handle civil cases fairly in accordance with the provisions of the Civil Procedure Law, thus realizing the trial function of the people's courts.

Second, it is conducive to effective supervision of trial activities. The trial puts the trial process of the case under the supervision of the people, which increases the transparency of trial activities and helps to ensure the fairness of case handling.

Third, it is conducive to protecting the litigation rights and substantive rights of the parties. The civil procedure law fully stipulates the litigation rights of the parties and the ways to exercise these rights in the trial. Trial is conducive to the parties fully exercising their litigation rights, consciously fulfilling their litigation obligations, ensuring the smooth progress of trial activities, and ultimately protecting the civil rights and factual rights of the parties.

Fourth, it is conducive to giving full play to the educational role of trial and expanding the publicity effect of the legal system.
