What do you mean, Cuckoo urges Laoyan to protect the farmland?

1, because cuckoo sounds like cuckoo, which is the season of spring ploughing in farmland. These birds seem to remind people of spring ploughing. So it's called "pushing cuckoo".

2. "Laoyan" is an image in China's poems, which means hardworking swallow, and can also be compared to hardworking and brave people.
