1. Matching of education level and resources: The first volume of the new college entrance examination corresponds to areas with relatively high education level or rich educational resources. Hunan, as a major education province in China, has strong education quality and resources, and the adoption of one volume can better match the education level and examination ability of students in this province.

2. Fairness and unification: The adoption of national unified examination papers will help to ensure the fairness of examinations between different regions and reduce the inconsistency of examination difficulty caused by regional differences.
