Chen Liang frowned even more. Gu Dajiang smiled and said, "It's like how you work hard in the fields all day for your family's food, clothes, and transportation. You work very hard and wish you could stay in the fields 24 hours a day. But is that possible? If you don't come back to rest when the weather is hot, you will suffer from heatstroke. If you work for too long, you will be tired. The hoe in your hand might even hit your toes, right?"
"It's the same for reading. If a person doesn't rest and reads all day, his eyes won't be able to take it. His thoughts will be chaotic for a long time and he won't be able to learn at all. The appropriate rest is for better work or learning in the future. Don't you think so? If you force students to read and write, it will backfire."
With this explanation, Chen Liang felt much easier to understand.
