Schools of Nangtong, Jiangsu Province start the morning classes an hour later than before. That’s, they begin the first class at about 8:30 a.m. This helps students feel less tired. The students are happy about the change.

Liu Ming said,“I’m glad that we don’t have to get up so early.”

Wu Hongli feels the same. She said that would be good for her health. “I used to get up at 6:30 a.m. I had to drink coffee every night, or I would feel too sleepy to finish my homework, ” said Wu.

Many teachers agree that the change helps students learn better. “Students used to doze(打瞌睡) in the first two classes in the morning,” said Huang Shan, an English teacher. “But now they are full of energy in class and learn much better than before.”
