I want to talk about some situations in our country and I have always had some pointopinions on ithem.

The opinions are on the situations, so you have to use the plural "them" rather than "it."

I don’t know if there is a situation in your country.

This is grammatical, but to me, "situation" without any context here suggests "problem" or "issue" in a general sense. "Similar situation" would make more sense to me, but it doesn't have the same meaning necessarily.

When it’s the end of the year, our department is required to bookorder a lot of next year’s newspapers and magazines.

If you mean by "book" you had a verb like "訂" in mind, note that "訂" translates to "order" when it's referring to things like magazines, inventory, etc. This is another explanation: https://www.reddit.com/r/EnglishLearning/comments/ansioh/whats_the_difference_between_to_order_and_to_book/

They are published from all levels of the departments of governments.

"All levels" to me already suggests that it's probably from all sorts of different departments. Alternatively, you could write something like "all levels of government departments."

For example, the publications may be Party Style and Clean Government, China’s Discipline Inspection and Supervision, Yingzhou Evening News and so on.

This didn't have a subject and so was a sentence fragment. A subject and verb should be added in, as I've done here, or it should be combined with the last sentence.

The cost of this kind of costthing every year is almost around ten thousand yuan.

We just put it alonthem aside and some day sell them as waste.

This kind of situation really makes us sad, but we can do nothing about ithis.

The publishers belong to every high authority department, and these departments are our lead-ranking departments.

"High-ranking" already suggests both things, so it's better to condense it.
"High authority" doesn't work as an adjective; instead I would write "every department with great [=much] authority," were I to keep the original structure.
"Leading" as an adjective suggests "best." If you meant to say that, rather than to say that those departments have authority and direct others, "most productive" would be clearer.

For instance, China’s Discipline Inspection and Supervision is issued by the CPC Central Commission for Discipline Inspection and you. We all know that it’s the department focusing on each official behaviorconcerned with the behavior of government officials, and everybody who works in a department that is funded by the government is afraid of it.

To avoid multiple instances of "and" to separate clauses, it's better to separate it into different sentences.
I think "we" is better than "you" here, since you wrote "everybody" later and since you yourself are included in "everybody." I might also replace "we all know" with "everybody knows," but this is also fine.

Our district party committee also has its Ddiscipline inspection committee.

If you want to instead use "Discipline inspection committee" as a formal name from Chinese, then each word should be capitalized, like they would be if it were a title, because they're all nouns.
(The main exception that comes to mind is if you're using a untranslated name from another language that already uses Latin characters, in which case I would keep the original capitalization. In the case of Chinese, that isn't relevant.)

And iIt is the department that requires us to bookorder that magazine.

Generally, one should not begin a sentence with "and," unless one is writing in a certain literary style. Beginning sentences with conjunctions in general is often discouraged, but I think there is more flexibility with others, like "yet" or "but."

Who dares refuse its demand?

Except[…] unless you want bad things to happen.

"Unless" is a subordinating conjunction, so the clause with it can't be a standalone sentence. This should be combined with the last sentence. The same goes for "except," but "except" doesn't really work here. "Unless" introduces clauses, while "except" tends to introduce nouns, gerunds and infinitives, adjectives, etc.

Because nowadays, access to information is particularly developadvanced and you can get a lot of information on your phone, and very fasquickly at that.

"Developed" is fine, but if I kept it, I would phrase it as "is highly developed" rather than "is particularly advanced."
"Fast" can be used as an adverb, but "quickly" sounds better to me.
"At that" is needed here because the adverb is separated from the rest of the clause.
