Long, long ago, a rabbit named Giang was living with his sister in their burrow. They used to go to Dolu’s house to read where Dolu’s brother taught them. Giang always asked Dolu’s brother many questions. One day Giang started asking many questions which made Dolu’s brother irritated. He sent him away. So Giang became very sad and thought, ‘Why do I get all these queries?’ His queries were—why is the sky blue?
Why are rabbits and snow of the same colour? Seeing him sad his sister Foamy, who was so smart, came to him and asked the reason of being so sad. Giang told her all the matter; then Foamy gave him a book and said, “Read the book which gives her all the knowledge which may clear his queries.”
