Stationed on the outskirts in Japan, after a few months' careful observation, the Chinese artist created the book about natural ecology. The book takes a small animal — the small plover as the main character, depicting their living condition and the relationship between them and nature, telling about the fortitude of life.

In April, the little plover flies back. She builds a little nest amidst the gravel and lays three tiny eggs. One day, when the little plover is out foraging, a huge crow jumps out at the nest and grabs the tiny eggs away. The little plover is so sad about her eggs and her failure to fight against the crow. She has to find somewhere else to start from the beginning. After months of careful preparation and safeguard, this time her little plover babies are born safe and sound. After overcoming various difficulties like the insecticide incident and the night cat risk, the plover babies are turning into fully fledged grown-ups. On a sunny day after the rain, a group of little plovers fly against the rainbow, saying goodbye to their mother land, and heads right towards the vast ocean.
