After the certificate is issued by the CMC, it shall be extracted from the escrow unit according to the balance of the maintenance fund subsidiary ledger. Among them, if it belongs to the after-sales maintenance fund of public housing, it shall be returned according to the cumulative proportion paid by units and individuals.
