Child theme with several styles…

How to work a child theme when my theme have style.css in main folder and then /assens/main.css in other folder??

This is my function:

function theme_enqueue_styles() {
wp_enqueue_style( ‘parent-style’, get_template_directory_uri() . ‘/style.css’ );
wp_enqueue_style( ‘child-style’, get_stylesheet_directory_uri() . ‘/style.css’, array( ‘parent-style’ ) );
}

add_action( ‘wp_enqueue_scripts’, ‘theme_enqueue_styles’, 99 );

Thank you
