Good morning，teachers and classmates！The Public Health Day is coming.Then how can we students live a healthy life
First，we should keep our bodies healthy.We should eat healthy food and take more exercise.Try to eat vegetables every day.I think taking a walk after dinner is great.We also need enough sleep every day.That gives us energy for the next day.
Second，mental health is also very important.We should love our life and try to be nice to others.Make friends and help them when they have problems.
I hope everyone can keep healthy and enjoy a happy life.It's never too late to start.
