How did Orid become a state-owned enterprise?

Change of creditor's subject. Orid is the major shareholder of Harbin Star Enterprise, but it is only a part of individual industrial university groups. Zuo Hongbo is the head of academic research in the Department of Materials of Industrial University. After Jianghai was acquired, the property group allocated four enterprises to Harbin Investment Group in the name of mixed reform of state-owned enterprises, because the creditor was changed to Harbin Investment Group.
