The reason why the national college entrance examination does not need a piece of paper;

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, with developed economy and rich educational resources, while China has a vast territory and rich resources, which has caused the imbalance of educational resources in various 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 questions.
