Is there something fishy about public bidding for property?

There is something fishy about public bidding for property. According to the provisions of Article 10 of the Bidding Law, bidding is divided into open bidding and invitation bidding. Open tender means that the tenderer invites unspecified legal persons or other organizations to bid by means of tender announcement. Invitation to bid means that a tenderer invites a specific legal person or other organization to bid in the form of an invitation to bid.
