Because of regional differences, since the birth of the imperial examination system, Zhejiang and Jiangsu have been the provinces with the largest number of champions in history, and Zhejiang and Jiangsu have been the places with the largest number of champions since ancient times. The reason is that these two provinces have been the richest places since ancient times and are rich in educational resources. China has a vast territory and abundant resources, resulting in the imbalance of educational resources in different regions. There will be obvious differences in education level. As long as the imbalance of educational resources is not improved, there will be no way to use the same college entrance examination papers throughout the country.

Since 2002, China's college entrance examination papers are no longer unified nationwide: provinces with relatively close basic education development levels use the same set of examination papers, such as Sichuan and Yunnan, while Hubei, Hunan, Hebei and other provinces and cities use the same set of examination papers because of their relatively close basic education development levels; Beijing, Shanghai and Tianjin are independent propositions because of their developed economy and excellent education. So generally speaking, the national college entrance examination papers are different.
