This is a film that truly reflects the life of penguins. The north of the Antarctic continent has a mild climate and plenty of food, while the south is covered with snow, cold and short of food all the year round. But the south also has its advantages, that is, it is ecologically stable and there is no pursuit by natural enemies. In order to make the baby penguins grow healthily, penguin parents come from the north to the south to hatch their eggs every year. Father and mother penguins take turns to incubate their eggs, while the other travels thousands of miles to find food. The hardships on the way are unbearable to anyone, and the frail penguins carry out this arduous task every year. The tenacious vitality shown in the film is thought-provoking.
