Welcome back to school. I'm excited to see you again. We might be scared or upset when facing the COVID-19 outbreak. But we were also strong and helpful. Many common people including you teenagers are playing an important role in the fight. All of us stayed at home in order to cause no trouble. You even finished an unbelievable event that never happened before, studying online at home. Thank you all.

As we all know, spring always puts an end to winter. Thanks to our great country, the classes finally shifted from online to offline. Enjoy your school life from now on. But in the special time, we have to follow the rules around the school.
