Prose about phenology, the more vivid the better?

If swallows fly high in the air and look small, there will be fine weather. A crow with a white beak flew in and said that spring had arrived at the gate. Flying cranes can tell people that the hot weather has passed without a calendar.

Look at the white clouds in the sky that day /This is the language of nature:/White clouds are floating high. /It must be sunny tomorrow.

Look at the ants on the ground. /This is also the language of nature:/Ants are busy moving,/Take an umbrella when going out.

Tadpoles swim in the water. /Is it like a black comma? /Nature writes on the water:/Spring comes to the world.

These geese are flying south in formation. /Isn't it like a string of ellipsis? /Nature writes in the blue sky:/Autumn is just around the corner.

If the tree is cut down,/you will find annual rings-/only one annual ring grows,/this is a natural language.

If you catch a big fish,/there are rings on the fish scale-/one year old,/this is the language of nature again.

Nature embeds trilobite fossils in the Himalayas. /This is telling people:/It used to be Wang Yang.

Nature planted a "boulder" on Lushan Mountain in the south of the Yangtze River to remind everyone that there was a cold glacier here.

You have learned to read for a long time, and you can easily read any sign on the street. You won't go to the barber shop to buy medicine, and you won't go to the drugstore to get a haircut. If no one is with you, you can easily find your way, just give you the correct address, street name and house number.

Words are really good things. If you know this word, you can read the thickest book and know everything in the world.

But there is another set of words that everyone who wants to be really knowledgeable should know.

This is the writing of nature. It always has thousands of letters. Every star in the sky is a letter. Every pebble under your feet is also a letter.

For those who don't understand this writing, all stars are the same thing. However, some people can recognize the names of many stars and tell how they are different from other stars.

Just as the words in a book are composed of letters, the stars in the sky also form constellations.

Since ancient times, when sailors need to find their way at sea, they will read books written by stars. You know, boarding a boat on the water just leaves no trace, and there is no road sign with an arrow that says "Go north from here". But sailors don't need such signs. They have a compass with a phosphorus needle, and the magnetic needle always points to the north. Even if they don't have a compass, they won't get lost. They looked at the sky and found Ursa major in many constellations, and Polaris was also in Ursa major. The north is beyond Polaris.

Clouds are also the letters in the big book of the sky. It talks about the future as well as the present. In the best weather, according to the clouds, thunderstorms or lewd rain can be predicted.

Sometimes, in hot summer, a white Yunshan stands in the distant sky. Two sharp points protrude from this Yunshan to the left and right. The mountain has become like an anvil in a blacksmith's shop.
