Try to write four agricultural proverbs and talk about the phenological knowledge contained in them.

Many agricultural proverbs handed down from ancient times contain rich phenological knowledge. For example:

△ Smell cicadas in the rain and forecast sunny days.

△ Smell cicadas in early autumn and welcome Tian Yu in late autumn.

△ Sparrows will fall snow when they eat.

△ It's going to rain in the ant nest.

△ Fish dive, rain is coming.

△ Swallows fly low and rain.

△ Toad comes out of the hole, and it keeps raining.

△ Turtle back tide, rain omen.

△ Earthworms climb the road, and the rain is chaotic.

△ Loach is quiet and sunny.

△ Pigs with grass, cold wave.

△ Chickens stay late, ducks shout happily, and wind and rain are coming.

There is also a saying in my own place (Shanxi) that "the sunset goes to Wan Li Road and you don't go out at dawn", that is to say, if there is a sunset, the next few days will be fine weather with clear skies in Wan Li; If the morning glow appears, the weather will get worse, which is generally accurate, hehe.
