How to make a link Read More after inserting More tag?

Hi guys! Can anyone help me in this matter? I need that after at the beginning of the article I put the tag Read more, there is a button read more. I made a child theme and pasted such code in functions.php

add_filter (‘excerpt_more’, ‘new_excerpt_more’);
function new_excerpt_more ( more) { global post;
return ’ '. __ (‘Chati dali’). ’ → </ span> </ span> ';
}

The button is visible only when I do not put the read more tag in the wordpress editor. But when I put the tag, the button is not visible, just the post is clipped without a link to the article.
