As a fan of online literature, I can't express any opinions on the policies of the Ministry of Education. However, from what I know about online literature, the importance of sleep time is very important for the growth and development of teenagers. Having enough sleep can strengthen their immunity and mental state, improve their attention and learning ability, and help them better adapt to the pressure of learning and life. In novels, it was common to see characters losing their competitiveness and vitality due to physical and mental weakness and fatigue due to lack of adequate sleep. Therefore, increasing the students 'sleep time in the novel might become an attractive plot setting to highlight the health and vitality of the characters.
