Only Category on Post page in Twenty Sixteen child theme

Hi,
I’m working with a “Twenty Sixteen” child theme. And use the posts as news in a static website. Now I get all messages, as expected neatly in a row on the news page. But I would like to see only posts with the category “General News”.

My question: How do I change the code below so that I only get post in the categorye “general news” on this page?

<?php
  the_excerpt( sprintf(
  __( 'Continue reading<span class="screen-reader-text"> "%s"</span>', 'twentysixteen' ),
  get_the_title()
  ));
?>

Code from: “/template-parts/content.php”.

Thanks for the help.
