My grandfather and I are coaches.

After the summer vacation, my grandfather asked me to go to the Hexi Swimming Pool as a swimming instructor.

I came to the swimming pool and saw so many people. I asked my grandfather that these people are all students? Grandpa answered yes. Let's do the warm-up exercises first, the left team, the right team, I teach them to do in the middle, and we will swim in the water. I helped the child who couldn't swim, and helped his hand drift. I walked in the water, and he floated in the water. They study hard, I teach seriously, it is really difficult to be a swimming coach!
