In the game, if the equipment is signed, it cannot be retrieved. Signing is a way to prevent the equipment from being stolen or misused, but once the signature is successful, the ownership of the equipment will be transferred to the buyer's account, and the seller will not be able to get the equipment back. So when trading equipment, you need to carefully consider and confirm the operation.

It should be noted that there are many types and quantities of equipment, and the specific provisions may be different. Before trading equipment, players are advised to read the relevant rules and instructions in the game carefully, or consult the official customer service of the game for details.
