I'm Li Hui. March will be a very busy month for me. I have many things to do. My brother's birthday is on March 9th. I will have a big birthday party for him. And I will buy some presents for him. The school trip is on March 12th. That's Tree Planting Day. I will plant trees with my teachers and classmates in the park. On March 23rd, I will have a maths test. Oh, what a busy month!
