Hearing the bell ring, I got up, quickly dressed me and ran onto the playground. A few minute later, more people came. They worked out for various ways. Some ran around the track. Some played basketball, tried to shoot baskets. A group of girls were walking on the balance beam in the turn. A couple of strongly-built boys made graceful movements on the flying rings. However, dozens of old men and women showed up, some of which did Taiji. At exact 6:30, music came for people to do exercise to radio music.
