Hello! Invitation to offer, also known as "invitation to offer", refers to the expression of intention that others want to make an offer to themselves. Invitation to offer is the preparatory behavior of the parties to conclude a contract. It only induces others to make an offer, and cannot form a contract because of the other party's promise.

According to the provisions of Article 15 of the Contract Law, if the inviter withdraws the invitation after the invitation to offer is issued, as long as it does not cause the loss of trust interests to the bona fide counterpart, the inviter generally does not bear the responsibility.
