Since the requirements of inventory management were put forward in the meeting in mid-2014, the group and its subsidiaries have always promoted inventory management as an important work. In the past two years, the company has been repeating the concept of inventory management through economic analysis meetings, special meetings, websites, internal journals and other ways, and developed the inventory management system applicable to each sector. Since last year, the group has formally listed inventory management as an important indicator of the annual assessment of the general manager.
