Winter vacation is both happy and full. With the footsteps of the elderly, let's enter the intense study!

The winter vacation is coming, which the students are looking forward to most. Time belongs to them completely, but there is one thing that can't make them have fun, and that is winter vacation homework.

I went to sleep when I knew it, and I slept very quietly. When busy, enjoy this quiet summer, that charming summer night, and enjoy every happy day. Even God is proud of me and spent a perfect summer vacation with me, a happy summer vacation.
