How to display parent category in joomshopping?

Question

Joomla

There is the following structure
Our works (id1)
- Interior (id2)
- - - Work 1
- Exterior (id3)
- - - Work 1
Product catalog (id4)
- Manufacturer 1 (id5)
- - - Products 1
- - - Products 2
- Manufacturer 2 (id6)
- - - Products 1
- - - Products 2
All this is built on joomshopping. It is necessary that for products that have the parent category Our works (id1) one style is displayed in the template, and for all the rest others. I'm trying to get this parent category on the product page, but I don't have the skill :) Subcategory Id I get $cid = $this->category_id; but how to get the parent category?
