Hello.
I’m going to insert some code line in Single.php.
I know content-extension.php is running as a Single.php in this Theme.
This file is in structure <- inc folder.
I want to use/modify through an Alias file in Child directory.
How can I make a content-extension.php in the Child-Theme?
Can I make ‘(interface-child)-> inc -> structure-> content-extension.php’?
I’m doing it. But I can’t run my procedure through modifying a content-extension.php in Child directory.
How can I set/write any code line in Function.php of Child-folder?
Of course, I read ‘https://developer.wordpress.org/themes/advanced-topics/child-themes/&#8217;. But I can’t it.
I want to know directly here the code/ way for using content-extension.php in Child-Theme.
All the codes in my Function.php:

<?php
add_action( 'wp_enqueue_scripts', 'theme_enqueue_styles' );
function theme_enqueue_styles() {
wp_enqueue_style( 'parent-style', get_template_directory_uri() . '/style.css' );
wp_enqueue_style( 'child-style', get_stylesheet_directory_uri() . '/style.css', array('parent-style'));
}
?>

too difficult.
Actually, I want to change/add a line in content-extension.php.
<br><span id='view_count' class="highlight">&nbsp;<?php echo do_shortcode( '[jp_post_view]' ); ?> &nbsp;</span>test<br>

But If I use an Unhook-Function in Fucntion.php, All the original function lines will be changed?
I need to insert only that line into 299 line.
299 line is included the function ‘interface_theloop_for_single’.
When I applied the following code in Function.php it didn’t work and crushed.

// Unhook default Thematic functions
function unhook_thematic_functions() {
    // Don't forget the position number if the original function has one
remove_action( 'interface_theloop_for_single');
}
add_action('init','unhook_thematic_functions'); // removes the header content by using hook interface_header
add_action( 'interface_theloop_for_single', 'interface_child_theloop_for_single');

function interface_child_theloop_for_single() {
	global $post;	
	global $options, $array_of_default_settings;
 $options = wp_parse_args( get_option( 'interface_theme_options', array() ), interface_get_option_defaults());

	if( have_posts() ) {
		while( have_posts() ) {
			the_post();

			do_action( 'interface_before_post' );
?>
<section id="post-<?php the_ID(); ?>" <?php post_class(); ?>>
  <article>
    <?php
				if( has_post_thumbnail() ) {
					$image = '';        			
		     		$title_attribute = apply_filters( 'the_title', get_the_title( $post->ID ) );
		     		$image .= '<figure class="post-featured-image">';
		  			$image .= '<a href="' . get_permalink() . '" title="'.the_title( '', '', false ).'">';
		  			$image .= get_the_post_thumbnail( $post->ID, 'featured', array( 'title' => esc_attr( $title_attribute ), 'alt' => esc_attr( $title_attribute ) ) ).'</a>';
					$image .='<span class="arrow"></span>';
		  			$image .= '</figure>';

		  			echo $image;
