What do you mean by a sudden surprise on your head?

Suddenly: suddenly.

Suddenly, there was a cloud and rain on my head: suddenly, the rolling dark clouds with showers sprinkled on my head.

From: Two Rains on the Stream by Cui Daorong in Tang Dynasty.

Back to the pond, the feet of the rain are like reeling, and wild birds can't afford to fly.

If you don't have time to plow and fish, Akita will probably drip.

Sit and watch the dark clouds and heavy rain, and spray mountains in front of you.

Suddenly, there were dark clouds overhead and it was stormy, but it was the night before the mountain came out.

Translation:

On the surface of the winding pond, the rain seems to be spinning. Wild birds can't take off because of the heavy rain, but the fish jumped onto the water in surprise. Farmers and anglers have no time to get hemp fibers and hats, and the fields in autumn are looking forward to such a hearty rain.

I sat there and watched the thick dark clouds in the sky spraying rain on the mountain ahead, but it was still sunny here. Suddenly, the rolling dark clouds with showers sprinkled on my head! However, I was surprised to find that there was a faint sunset on the green peak ahead!

Extended information poems are different from ordinary Tang poems. It's about the rainstorm in summer, from which we can't find any meaning, nor can it be regarded as a portrayal of the author's mood. Because he really wrote rain for the sake of writing rain. Finding a strange emotion from observing and thinking about a natural phenomenon is one of the many inventions of Song people in "summarizing and wrapping" poetry.

As far as the artistic technique of poetry is concerned, it does not conform to the usual implicit expression technique of Tang poetry, and there is no concise and clear brushwork of writing scenes with reality and reality. His style of writing can be summarized in eight words: bad looks and quick hearts.

Summer rain is characterized by rapid onset, strong strength and uncertain feet. These points were accurately grasped by the poet and expressed in his works. The torrential rain was just in front of the mountain, and suddenly it came to the stream, which made people unable to avoid it and came very quickly.

Sometimes it rains in the east, sometimes in the west and sometimes in the east. I also wrote a natural wonder caused by the rapid transfer of rain feet. That's not enough. Poets also "sit and watch" and then "suddenly surprised" through the expression changes of people who "meet the rain", which shows that the sudden change of summer rain is unpredictable. The whole idea is agile and flexible, the pen is fresh and lively, and the words are sharp, novel and gratifying, which has won Xia Yu's interest.

As far as the similarity of the scene is concerned, this poem focuses on two places ("Qianshan" and "Xiaoxi"), which have both the changes of scenery in different periods and the spatial contrast. For example, in terms of the rhyme of poetry, Su Shi is better; As for the novelty of the structure, this poem is not suitable for making more concessions.
