How did some students and tutors find shortcuts to learning? How did the Chinese government react to these shortcuts?
kotykmax [209]

According to an alternative source, this question pertains to the text "The Chinese Civil Service Exam System” authored by Ichisada Miyazaki.

This text reveals that the civil service exams in China originated almost fourteen centuries ago, making it one of the oldest examination systems globally.

The purpose of this system was to identify the most talented young men in China for governmental roles, providing them with the necessary education. However, this process was lengthy and arduous, prompting many students and teachers to create effective shortcuts for exam preparation. For instance, rapid study techniques were developed, including compiled answer collections for exams.

Such methods were known to the Chinese authorities, who condemned them vehemently. Students utilizing these shortcuts faced failure, and the government frequently banned the publication of such resources. However, the business of producing these materials was thriving, leading to the ineffectiveness of these bans.
