Hello, everyone,
I will tell you some informations about our school’s opening ceremony. It was held on September 10. It was sunny. More than 6,000 teachers and students took part it. There were very many people that we had to walk slow. It was a two-hour ceremony. The opening ceremony was really excited to us, because they met a number of new students and teachers. With our teachers’ help, we made a great progress in each subject, so we sang and dance happily. Although we were very tired, but we were excited. I’m looking forward to receive your reply.
