Childlike, I understand it as the fun of childhood. Fun is mostly interesting things. Who didn’t have a few such things in their childhood? I spent my childhood in the suburbs of Beijing. The most interesting things that I remember all happened in the summer. Summer evenings are the happiest time for children in the alley. After dinner, everyone will run to the street in unison. Sometimes there are about ten, sometimes as few as four or five. What are these children playing with? Hey, there are so many ways to play! On both sides of the street, there are always people who want to build houses, and adults always pile a large cart of sand on the street. This pile of sand, which is almost as high as the house, has become the children's favorite. Groups of children quickly climbed to the highest point of the sand pile. Digging holes in the golden sand, playing with each other, and having so much fun. Some children don't like to play with everyone and just crawl around silently on the sand. This tall pile of sand, like a small building, must have been much shorter during the day the next day. Therefore, he often attracts scolding from adults. "Go, go, play somewhere else!" After they shouted, some children slipped down, and after the adults left, they climbed up again. If you do this again and again, no one will come to "drive you away" again. Piles of sand don't happen every day. So the children went to catch dragonflies in the summer evening. There happens to be a river next to the railway in the suburbs. This river is not far from home. Both sides of the river bank are crowded with various water plants. They are dense and lush. The river water can reach our knees. We were holding long bamboo poles in our hands. The top of the pole was covered with homemade glue, which was used to catch dragonflies. If it is daytime, we will carry the broom, stand in the river, shake it in the air a few times, and many dragonflies will fall into the water. There were so many dragonflies at that time. It had just rained, and the dragonfly was flying low, its transparent wings dangled in front of your eyes, and you could catch it with your hands. When there were dragonflies between our fingers, we happily went home together. That river shaped many children’s childhoods. There are many more interesting things about my childhood, just around the river, there are too many to mention. However, the beautiful childhood is as short as summer. Now that the river has dried up, I think maybe it exists just for us. When we grow up and everything changes, it should also feel lonely. However, the playmate also didn’t know where he had gone.
