What is the administrative level of Henan Coal Chemical Group?

Henan Coal Chemical Group (merging Zhongyuan Dahua, Yongmei Group, Coking Coal Group, Hemei Group and Coal Bed Methane Company) is now a provincial large-scale enterprise with the main hall level. Although Yongmei and Coking Coal used to be departmental level, they will still be departmental level after the merger, but the power of the chairman has increased. Maybe the bosses of these five companies will go back to the province, and there will be a surplus.
