I sold something on the idle fish, and it has been delivered. What if the other party says that I am selling fake goods or returning some garbage to me?

First of all, there are many kinds of buyers: 1. Could be the real buyer. He wants to make a counter-offer, but he won't pay for it. He will make a counter-offer with you and let you modify the price. If you think he is sincere enough to accept the counter-offer, he will make a move and pay until the transaction is successful. 2, it may be the "trust" in idle fish, I don't really want to buy your things. I just want to "swipe my bill" or something. Generally, I will shoot it soon after you release it without paying, and then make a counter-offer with you. If the deal is made, you deliver the goods, he receives the goods, and then sends you a picture saying that your goods have problems and other reasons to refuse the goods and apply for a refund. Generally, Taobao will intervene after 7 days. If there are some problems with your goods, Taobao will stand on the buyer's side and support the buyer to refund, and then they will successfully complete the task. And you sent the goods and brought them back, accompanied by the postage paid. 3. If you meet someone who doesn't pay for a quick photo, click on his head to see if his address is from Wenzhou, Zhejiang. If it is, it is probably "Tuo". Never deliver the goods.
