woocommerce: join post and product category

I’m working on a e-commerce website and I would like to know if it’s possible to have the same category for posts and woocommerce products ? I would like to get both articles and products from specific category. I’ve tried this https://wordpress.org/support/topic/relating-a-post-to-a-product-category which make products categories appears in posts but I don’t know how to display them in posts loop.

<article <?php post_class(); ?>>
  <header>    
    <h2><a href="<?php the_permalink(); ?>"><?php the_title(); ?></a></h2>

    <?php the_tags('<ul class="entry-tags"><li>','</li><li>','</li></ul>');
    the_category( ' ' ); ?>
  </header>

<div>
   <?php the_excerpt(); ?>
    <?php if ( has_post_thumbnail() ) { 
    the_post_thumbnail();
    } 
    ?>
</div>

</article>

Thanks in advance.
