Write a 450-word composition to help other children find their mother in the park.

After dinner today, my mother and I went to the Cultural Square to play. Many people come to play on weekends, some are walking, some are skating and some are dancing. ...

My mother and I jog around the cultural square first, and then go to the stage to watch the dance. Suddenly, we saw a little girl crying and looking around. The little girl is about 4 years old and wears skates. I asked curiously, "Little Sister, what's wrong with you?" My little sister cried and said, "I got separated from my mother while skating!" " "At this time, people around you gathered around and some asked," What does your mother look like, little friend? Someone asked, "where do you live, little friend?" "Everyone is trying to help her.

After understanding the situation, the police uncle told his colleagues to help find the little girl's mother with the walkie-talkie. After a while, an aunt came running from a distance. The little girl shouted "Mom, Mom!" "Jump into the mother's arms. Everyone laughed happily.
