Does Zhongshan Huaying Industrial Investment belong to Shenzhen SASAC?

Belong to. This company is actually a central enterprise, and the actual controller is the Shenzhen State-owned Assets Supervision and Administration Commission, so it is still relatively strong, and the general private company is definitely not as good as this company.
