At night, there is a bird called "Goo, Goo, Goo". The first two sounds are gentle, and then the second one is urgent. It sounds like knocking on a wooden fish?

Cuckoo is a bird that coos in the middle of the night. With the coming of the solar terms in Grain Rain, cuckoos began to crow. The sound of "cuckoo, cuckoo" is very similar to the pronunciation of "cuckoo, cuckoo", as if urging people to sow early, otherwise, people will mistakenly think it is a year. So we call this bird Rhododendron, which is vivid, and there is no better name in China.
