Xiao Niu has lost a tooth. She remembers Grandfather telling her that if a tooth from the lower jaw falls off, it must be thrown up to the roof so that she can grow tall. She takes her tooth to find grandfather and along the way we are treated to scenes of old alley ways and people at work and at leisure. We also get glimpses of tall and new buildings being erected as old buildings are being demolished. The illustrations are of old Nanjing City. According to the publisher, the book 'dwells on the custom of throwing the baby teeth of children onto the roof. The author links the custom with the theme of city changes: old alleys and houses are gradually disappearing with the old life style.'
It is raining heavily and the animals in the forest are looking for shelter. An ant saw a mushroom and went and sheltered under it. Then a butterfly comes along. "But there isn't space for you," the ant starts to say but then he looks sideways and sees perhaps there is a little space for butterfly. Then comes a mouse. "Please let me shelter here," he says. "But there isn't space for you," the butterfly says but then he sees, there is a little space for the mouse. This is followed by the sparrow and the rabbit. They all squeeze to make room for one another. How strange that a mushroom can shelter so many creatures! Gorgeous illustrations with simple repetitive text make the reading fun for young children.
