尝试这个代码。它会解决你的问题。

      <?php
        $post_categories = get_the_category(get_the_id());
        foreach ($post_categories as $post_category) {
            if( $post_category->parent == 0 ){
                //$parent_cat_link, $parent_cat_name contain base category link and name
                $parent_cat_link = get_category_link( $post_category->cat_ID );
                $parent_cat_name = get_the_category_by_ID( $post_category->cat_ID );
                //child_of attribute is your parent category id that will give you its child category 
                $cats = get_terms( array( 'taxonomy' => 'category', 'child_of' => $post_category->cat_ID ) );
                echo '<a href="'. esc_url( $parent_cat_link ) .'">' . esc_html( $parent_cat_name ). '</a> >>';
                foreach ( $cats as $key => $cat ) {
                    $cat_link = get_category_link( $cat->term_id );
                    $cat_name = get_the_category_by_ID( $cat->term_id );
                    echo '<a href="'. esc_url( $cat_link ) .'">'. esc_html( $cat_name ). '</a>>>';
                }
                echo "<br>";
            }
        }
        ?>
