How to display the custom excerpt only

Hi,

I have this problem and i searched for the solution for one hour and didn’t find any solution , However i see the solution is very simple.

I am using child theme of dynamic news lte theme

I want to display only the custom excerpt which i write by my self
If there wasn’t a custom excerpt , I didn’t want to display the auto excerpt .

I tried to make the auto excerpt zero string , but the pages loaded very slowly Especially the number of posts is 50 on one page.

in content-excerpt.php

<div class="entry clearfix">
			<?php the_excerpt(); ?>
			<a href="<?php esc_url(the_permalink()) ?>" class="more-link"><?php _e('Read more', 'dynamicnewslite'); ?></a>
		</div>

I need to change the_excerpt(); to the function which display only my custom excerpt .

also, is there any solution for this problem ?

Thanx
