University admission via comprehensive evaluation has played a great role in breaking through the "scores-only" shackles, implementing the mechanism of cultivating people by virtue, helping universities to select talents, and guiding primary education institutions to carry out education for all-round development. However, in practice, it faces some difficulties:utilitarian educational thinking constrains people's recognition of comprehensive evaluation admission; limited university enrollment capacity restricts the scientific development of comprehensive evaluation admission; and potential factors such as family cultural capital and educational resources affect the fairness of comprehensive evaluation. In order to further improve the comprehensive evaluation admission system, it is necessary to get out of the rut of exam-oriented education and improve ways for comprehensive evaluation. First, universities should establish a new education evaluation concept, and put comprehensive evaluation into practice. Second, they should improve their enrollment capacity and ensure scientific comprehensive evaluation admission. Third, they should give good publicity to the policy of comprehensive evaluation admission and expand its influence.
