Mei Mei and Xiaoxiao go to the park to play sandcastles. They had a good time. The sun went down. Meimei and Xiaoxiao are ready to go home. But suddenly, Mei Mei was in tears. The park manager's uncle asked her what happened. Mei Mei said, son, my child is gone. Uncle management and everyone are very strange. Smile and talk to the management uncle. The smiling shoes are gone. Oh! ? I see! Uncle management went to the sand castle and found beautiful shoes. It turned out that the shoes were covered with sand. Kid. Speak fluent Mandarin outside, huh? Don't speak dialects like Mei Mei. What can I do if I don't understand?
