During 2018, Planora drew up a development plan for district heating operations in the city of Changua on behalf of the Dunan Group. The work was successful, and Dunan decided to build the Sino – Finland District Heating Demonstration Area. To declare this demonstration area, a “regional shield” was unveiled at an event in Changyuan on May 25, 2018. Below is a picture of the unveiling of the shield and the shield.
