The hero of this story is a mentally retarded child, but in the childhood "hide-and-seek game", Xiao Yong was never regarded as a mentally retarded child. He sincerely devoted himself to the collective games of his childhood, and his thoughts and behaviors that did not belong to normal children were never regarded as alien. The author truly and accurately grasped the vision of childhood. When Xiao Yong had to leave these to him.
When he was a happy childhood companion, he "hid" on his own. This is a special way for Xiao Yong to express his attachment to his companion. Children's hearts are linked together, and Peekaboo King became the best farewell speech for friends and Xiao Yong.
In real life, I once had a similar experience with Xiao Yong. I remember I used to be a girl with low self-esteem and lack of courage. I dare not do anything and have no confidence to do it well. I always like to shut myself in the corner. Fortunately, with the selfless help of teachers and classmates around, my ugly duckling turned into a beautiful swan. Students, each of us will have some defects more or less, but we can't discriminate against others and stay away from them because of their shortcomings and imperfections. We should reach out to help them and let them regain their courage in life!
