The physical picture is as follows

buyers must see:
inspection receipt-after the buyer receives the goods, please check the goods before signing. If the goods are damaged, please reject them! Return to the courier company face to face! Please open the package personally to check the quality and count the quantity. If there is any discrepancy, please contact the seller immediately in front of the courier.
Sign first and then inspect the goods. If you have any questions, you can reject them (very important). Please see the following procedure:
1. Please sign the goods normally. Because if it is not signed, the package does not belong to you, and the courier dare not let you unpack it, otherwise it cannot be explained when you go back.
2. After signing, the list is in your hand, which is the key link. After signing, be sure not to let the courier tear the order away. Please open the package immediately for inspection
. If the order has been torn off, you will sign it and hold it in your hand first, or where the courier cannot get it, and then ask him to hand it to you for inspection. (You have signed as required, and he has no reason not to give you a package.)
3. If you have seen it and there is no problem, send the order to the Courier. Everyone is worried, the transaction is successful!
4. If any problem is found after the inspection, please stroke off the signature immediately and inform us by phone, then seal the package and ask the courier to reject it.
5. If the courier asks him to prove that it is not his unpacked bag, please help the courier. After all, people are also responsible for delivery. Even if there is a problem with the goods during transportation, don't embarrass the courier.
6. Please pay attention to the problems that may occur in the process of logistics transportation: the integrity of the outer packaging does not mean that the goods inside are complete, and does not mean that the goods inside are not damaged due to being trampled and squeezed, the integrity of the outer packaging does not mean that it is the original packaging when we deliver the goods. It does not mean that it has not been removed and repackaged. Therefore, be sure to check face to face and clarify responsibilities. According to the Postal Law, the corresponding responsibility of the recipient will be handed over to the recipient after signing, and any problems will occur after the courier leaves. According to the Postal Law, the logistics company has the right not to be responsible for any complaints or compensation requirements, therefore, in order to safeguard your legitimate rights and interests, please sign in person to keep the evidence, so that the responsibility is clear and convenient to solve.
