In this case you want to set a canonical URL to tell search engines that the content is duplicated over more than one URL. The canonical URL is a
<link> tag which appears in the
<head> of your page, for example:
<link rel="canonical" href="https://example.com/Tourism/astara/museum-customs-home-belgians" />
You want to use this same URL for each of the different category URLs, telling search engines which is the main source post.
The easiest way to do this is using a plugin, such as Wordpress SEO. They also have a Knowledge base article which will help you to set these up for your posts.
