McDull, a boy who is not handsome and has a plain mind. He and his mother, Mrs. McDull, live a not-so-rich but happy life in a place called Tai Kok Tsui, Hong Kong. From the moment McDull came into the world with his mother's expectations, his mind has been filled with colorful fantasy bubbles. The Maldives of his childhood with blue sky and white clouds, coconut trees, clear water and white sand, the tempting aroma of Christmas turkey, and the dream of winning the Olympic gold medal in "Bun Mountain" made McDull ordinary in his ordinariness, but happy in his happiness. McDull, together with the children of Springfield Flower Kindergarten, accompanied us and grew up slowly under the care of love.
