How to display posts on a specific page in WordPress?

Question

Taxonomy

Good day!
I had such a question, perhaps it is strange, I don’t even know how to formulate it correctly.
In general, on a site that is based on WordPress, there is a page, let's call it “Page 1”.
By default, when you create new posts in WordPress, they go to the main page (except when you put posts on a separate page in the settings).
How can I make sure that records of a certain category are displayed on the page - “Page 1” (as well as on the main page, only on this page).
For example: I have 80% of the posts that should go to the main page, but there are also 20% that should only go to the page - “Page 1”.
Perhaps there are some plugins that allow you to achieve this result.
Thank you in advance for your response!

Answer 1

Good.
And what for the output on "Page 1" is necessary? If you have already created a category, then you already have such a page. It is located at: http://site_address/category/category_label. It displays only records from this category.
To exclude the display of posts of a certain category from the main page, you can use the Ultimate Category Excluder plugin or its analogues.

Answer 2

Form a loop with the necessary records and display in the template.
