In a primary school of Yunnan, there' re over 500 students, but no one is nearsighted(近视). It's hard to believe. Three hours of outdoor play and no mobile phones or computers— this might be the reason why they all have good eyesight.
In the school, children eat healthy food and have enough sleep every day. During class breaks, all of them need to go outside. When the three sports teachers of the school are busy, other teachers will teach students to play basketball and table tennis.
To stop students from using mobile phones, the school had six public(公用的) phones for them to call their parents. Even on weekends and during holidays, the school tells parents to care about kids' eye health in teacher-parent WeChat groups.
Sun Fubiao, the primary school' s headmaster, tries his best to help students protect(保护) their eyesight, because he himself and five other teachers are nearsighted. "It' s uncomfortable to do many things wearing a pair of glasses in daily life, " he said. "I do not want the children to have the same bad experience. "

Schools can' t give homework to first and second graders. ____▲____ . But for them, it' s more important to go outside and play.
