How to show post which has the specific taxonomy terms?

Question

I am very new to coding.The following code is working fine which shows the post which has taxonomy "persons", but when I am using second part then it is not showing the content.What I want is to show the post which has the person and animal taxonomy terms.

   $terms = wp_get_post_terms( $post->ID, 'persons' );
$term_slugs = wp_list_pluck( $terms, 'slug' );

'tax_query' => array(
     array(
         'taxonomy' => 'persons',
         'field' => 'id',
         'terms' => $term_slugs
         )
     ),

Second part:

$terms = wp_get_post_terms( $post->ID, 'persons' );
  $term_slugs = wp_list_pluck( $terms, 'slug' );
$terms2 = wp_get_post_terms( $post->ID, 'animal' );
  $term_slugs2 = wp_list_pluck( $terms, 'slug' );

    'tax_query' => array(
         array(
             'taxonomy' => 'persons',
             'field' => 'id',
             'terms' => $term_slugs
             ),
           array(
             'taxonomy' => 'animal',
             'field' => 'id',
             'terms' => $term_slugs2
             )
         ),

Use this code instead.

$terms = wp_get_post_terms( $post->ID, array('competition', 'session') );
$term_slugs = wp_list_pluck( $terms, 'slug' );    
 $season = wp_get_post_terms( $post->ID, 'session' );
$season_slugs = wp_list_pluck( $terms, 'slug' ); 
$args = array(
        'post_type' => array( 'football_fixture' ), // profile and letter are CPTs
            'tax_query' => array(
                array(
                'taxonomy' => 'competition',
                'field' => 'slug',
                'terms' => $term_slugs
                ),
               array (
              'taxonomy' => 'session',
              'terms' => $season_slugs,
              'field' => 'slug')
            )   
    );


    $my_query = new WP_Query($args);
