How to display output field in Drupal?

Question

Drupal

Hello dear professionals.
First time working with Drupal. There is a need to display fields.
There is an arbitrary data type "book" in which there are arbitrary fields. Each book uses a separate design, so each book has its own template. To do this, I created a page--node--306.html.twig file - where 306 is the id of the material.
Tell me how now to display arbitrary fields in this file.
