problem with custom post type and custom taxonomy url structure

I create a tour custom post type and destination custom taxonomy like this:

<?php
/*********************************************** Create Post Type ***********************************************/
add_action('init', 'create_post_type');
function create_post_type()
{
    register_post_type('tour', array(
        'label' => 'تور',
        'description' => '',
        'public' => true,
        'show_ui' => true,
        'show_in_menu' => true,
        'show_in_admin_bar' => true,
        'capability_type' => 'post',
        'hierarchical' => true,
        'rewrite' => array('slug' => 'tour', 'with_front' => false,'hierarchical' => true,),
        'query_var' => true,
        'has_archive' => false,
        'exclude_from_search' => false,
        'supports' => array('title', 'editor', 'thumbnail'),
        'taxonomies' => array('destination'),
        'labels' => array(
            'name' => 'تور',
            'singular_name' => 'تور',
            'menu_name' => 'تور',
            'add_new' => 'افزودن تور',
            'add_new_item' => 'افزودن تور',
            'edit' => 'ویرایش',
            'edit_item' => 'ویرایش تور',
            'new_item' => 'تور جدید',
            'view' => 'نمایش',
            'view_item' => 'نمایش',
            'search_items' => 'جستجوی تور',
            'not_found' => 'تور وجود ندارد.',
            'not_found_in_trash' => 'زباله خالی است.',
            'parent' => 'تور والد',
        ),
        'menu_icon' => 'dashicons-admin-site-alt'
    ));
}

/*********************************************** Register Taxonomy ***********************************************/
add_action('init', 'site_register_taxonomy');
function site_register_taxonomy()
{
    register_taxonomy(
        'destination',
        array('tour'),
        array(
            'labels' => array(
                'name'              => 'مقصد',
                'all_items'         => 'همه انواع مقاصد',
                'edit_item'         => 'ویرایش مقصد',
                'update_item'       => 'آپدیت مقصد',
                'add_new_item'      => 'اضافه کردن مقصد جدید',
            ),
            'sort' => true,
            'args' => array('orderby' => 'term_order'),
            'rewrite' => array('slug' => 'tour', 'with_front' => false,'hierarchical' => true,),
            'show_admin_column' => true,
            'show_in_rest' => false,
            'hierarchical' => true,
        )
    );
}

I want this URL structure for taxonomy and single posts:

taxonomy: site/tour/parent-tax/child-tax

post: site/tour/parent-tax/child-tax/single-post-url

now I make taxonomy structure but it gets 404 error and I don't know how to make single post url structre.

Does anyone have a solution for this?
