May 1st is a sunny day. Liu Yang and I planned to ride to the park to play together. We only spent half an hour getting to the park. We took pictures, chatted there happily.But, just at that moment,we heard the sound of a life-saving,and then saw a little boy fell into the river. Without hesitation, Liu Yang and I jumped into the river and then took him to the hospital soon, the boy was saved. While we were very tired,my heart was full of happiness.
