Wordpress: Pagination displays the same content on each page

When I checked the website today, I found that all paginated pages in one category displayed the same content, while other pages were normal. The solution is to add the following parameters to the paging code:

'paged' => get_query_var( 'paged' ),

The final paging code is as follows:

     $cat,
            'post__not_in' => get_option( 'sticky_posts' ) ,
            'posts_per_page' => 10,
            'paged' => get_query_var( 'paged' ),
        );
        $query = new WP_Query( $args );
        while ( $query->have_posts() ) : $query->the_post();
    ?>
    

        
            
            

        
    
    

 3, 'prev_text' =>'<', 'next_text' =>'>') ); ?>
