How to combine these two code together. (Split product description & Add tabs) Debut Theme

[m2mmm2]

Hello there,

I am using debut theme.

I have got code 1 for Splitting product description. Code 2 for Add tabs.

Since Code 1 and Code 2 need to replace the same original code. It makes my content shows twice.. I think combine these two code would help. Many many thanks in advance.

Code 1 Splitting product description: 

<div class="product-single__description rte">
           {% include 'tabbed-description' %}
        </div>

Code 2 Add tabs

<div class="product-single__description rte" id="first_product_description">
      {{ product.description | split: '<!-- split -->' | first }}
          </div>
      </div>
    </div>
    {% if product.description contains "<!-- split -->" %}
        <div class="product-single__description rte" id="last_product_description">
      {{ product.description | split: '<!-- split -->' | last }}
       
      </div>
  {% endif %}

Original code on product-template.liquid

<div class="product-single__description rte">
          {{ product.description }}
        </div>

I wanna make this: https://m79hzwirmckh22ml-36542939273.shopifypreview.com/products_preview?preview_key=5a6b49cb9664d62... （not quite sure if you could open it, so I attach a picture below）
