Need help understanding this WP Query [closed]

You can try this code to show only post.

if(isset($xt_corporate_lite_opt['xt_about_page']) && $xt_corporate_lite_opt['xt_about_page'] != '') {
    $args = array( 'post_type' => 'post');
    $xt_query = new WP_Query($args);
    if ($xt_query->have_posts()) {
        while ($xt_query->have_posts()) {
            $xt_query->the_post();
            the_content();
        }
    }
    wp_reset_postdata();
}
