WooCommerce - 更改简短描述的简短描述

I want to use woocommerce_single_product_summary instead of woocommerce_short_description.

How to do that? If I just change "woocommerce_short_description", it still shows short description.

Thank you

<?php break;
   case 'description': ?>
      <div class="wcpc-compare-row">
         <div class="wcpc-compare-cell" data-compare="<?php echo $k; ?>">
            <div class="wcpc-compare-description">
               <?php $post = get_post($product->get_id()); echo apply_filters( 'woocommerce_short_description', $post->post_excerpt ); ?>
            </div>
         </div>
       </div>

if you want to get the product description instead of short description you need to use the following:

$post->post_content;

instead of :

$post->post_excerpt;
