Are the Provincial Cement Factory and Conch Cement Factory in Ningguo the same company?

Let’s talk about this slowly. A long time ago, there was a cement factory in Ningguo County, which belonged to Ningguo County. Later, people from Shanghai came to invest in a cement factory (referred to as the old factory). The benefits were good, so the county cement factory was cancelled. Later, the Shanghainese left, and the old factory returned to the local government. Later, the Anhui Provincial Department of Building Materials was in charge of expanding a cement plant based on the original old plant (referred to as the new plant). Later, the two plants were merged and came under the management of the Provincial Department of Building Materials, referred to as The Provincial Cement Factory, also known as Ningguo Cement Factory due to its location in Ningguo, established Conch Group with the improvement of efficiency and expansion of scale. Conch Group has independent operations and personnel relations and has nothing to do with Ningguo City. The production and operation has evolved from the original cement to multiple business projects including PVC building materials, hotels, etc. As far as the cement industry is concerned, there are factories all over the country and abroad with production and sales scales not less than that of Ningguo Cement Factory. In this way, Ningguo Cement Factory The cement factory became a branch of the Conch Group, so it was known as "Ningguo Conch Factory", "Zongyang Conch" and "Ningbo Conch". That’s all I know. Do you understand?
