Matched with Nguyen Trieu Trung Big Chum from 8/2015, Little Chum Tu gradually revealed his love for plants and animals, as well as his curiosity for the natural science phenomena around him through encouragement from his Big Chum. In the last “The book I love” competition, Tu turned from a shy boy to a very confident storyteller by telling the story, "The cat teaches the seagulls flying" and achieved second prize. "I love my Big Chum very much, and I want to do many good things to show him my efforts," Tu said.
