    There was an art festival in our school last weekend. It had been held for five years and our headmaster plan to make it a feature of our school. I was so excited, for it was first time for me to join in.

    Early in the morning, there were such many people coming to our school, made it so lively. The students gave a warm welcome to the guest. I walked around or appreciated the paintings. All the works were from the students and I was so impressing by them. There were also some handcrafts, that were so creative. Though we were busy with our study most of the time, but some students still managed to develop their hobbies. I should learn to them and develop a hobby as well.
