How to display a specific category in wordpress post by id or other

Question

I am trying to create a related post section at the bottom of each post. I am using YARPP plugin to generate the related posts. I want customise the a template to show, a thumbnail(Done), title(Done) and a specific category(Issue).

My issue is its displaying all assigned categories, I only want to display one child category. I have a speaker category with child categories of the names of the speakers.

Let me know if you need more information. Thanks

<?php $related = get_posts( array( 'category__in' => wp_get_post_categories($post->ID), 'numberposts' => 6, 'post__not_in' => array($post->ID) ) );
    if( $related ) foreach( $related as $post ) { setup_postdata($post); ?>
      <div class="post">

        <div class="post-title">
          <a href="<?php the_permalink() ?>"><h6 class="title"><?php the_title() ?></h6></a>
        </div>
        <a href="<?php the_permalink() ?>"><div class="post-img" style="background-image: url(<?php the_post_thumbnail_url(); ?>)"></div></a>
      </div>
    <?php } wp_reset_postdata(); ?>
