The Cuckoos Sing Too Late (1959)

Spring is here, and the cuckoo leads the children to fly to the mountain village as in previous years, calling "cuckoo", "cuckoo", wanting to remind people to sow grain seeds quickly. Its cry attracted good-natured ridicule from many animals and birds. They all said that it was late this year, and people had already sown the grain seeds, and now the seedlings have grown.
