The law of sufficiency in the composition: the most concise is the most sufficient, trying to discuss Zhu Ziqing's "Spring"

There is a passage in "Spring" -

There are more kites in the sky and more children on the ground. In the city and the countryside, every household, young and old, also rushed out, one by one. Shu live and rejuvenate the bones, shake the spirit, do their own part of the child's work...

In other words, the average person may habitually write "there are more children on the ground" or "there are more children on the ground", compared with the original sentence, these unsucuous parts [up], are unnecessary. Isn't it?

For the original text of "all came out one by one", I believe that many people will write it as "one by one came out of the house".

This will not only not help, but will return to the composition of the law of sufficiency, sliding to the composition to give the law. You can ask this question: Didn't he come out of the station? Didn't he come out of the mall? Didn't he come out of school?

So many "young and old" are predetermined, must they come out of the house?

Such a comparison shows what the law of sufficiency is.

[The most concise language is the most sufficient language] - this is the grammar of composition rhetorical sufficiency.

-- ,—— households in the city and the countryside,—— young and old,—— including everyone,—— which is a sufficient law of the content and form of the composition.

The Law of Sufficiency: including grammar and rhetoric, content and form.

Drawing a snake is not a law of sufficiency, or it may form a law of giving shields.
