He wrote many fairy tales and pantomime for children in his life, among which Peter Pan is his masterpiece and has the greatest influence.
After moving to London, Barry lives near Kensington Park and passes by there every day for work. One day, he saw some children playing on the grass. They build huts with branches, make snacks with mud, and dress up as fairies and pirates in fairy tales. The game attracted a black-bearded writer. He stood by and smiled. Later, a bold child asked him if he would like to play with them, so the black beard writer happily joined the children's game and played until dark. On his way home, Barry found that these children were all his neighbors, and the most active boy was named Peter. Later, the children heard from their parents that Barry was a writer and he was writing a play called Peter Pan, so they surrounded him and asked him to tell the story of Peter Pan. They didn't know they were all in the story until Barry finished speaking. Later, Barry called these children his creative collaborators. When Peter Pan was released, the children each got five pence!
After the premiere of Peter Pan in London, it caused a great sensation among the audience. Later, it was adapted into a fairy tale, translated into a variety of literary works and spread abroad. Comics, commemorative books, printed matter, stamps, etc. The film based on Peter Pan's story is very popular in Europe and America. Since Peter Pan was put on the screen, every Christmas, western countries will broadcast this program on TV as a gift for children.
