Compared with the strength of SDIC Coal Industry (Dengfeng) of Mei Zheng Group, which one has more development potential?

Mei Zheng Group is a provincial state-owned enterprise and SDIC is a central enterprise, but SDIC Dengfeng belongs to local management. If you are a child majoring in coal or want to engage in coal, I suggest you go to Mei Zheng, because it is an old enterprise specializing in mining, which is risky for SDIC, and it is not specialized in coal.
