A few days after the delivery of idle fish, there was a reply.

After the idle fish is delivered, the system will automatically confirm the receipt after 10 by default. 10 days later, if the other party does not confirm or apply for a return, the system will automatically pay the seller Alipay. Idle fish and Taobao are both transactions guaranteed by Alipay. Buyers pay, sellers deliver goods, fill out forms, and confirm receipt. Because idle fish, like Taobao, are guaranteed by Alipay, the money is temporarily stored in Alipay before the buyer confirms the receipt. After the receipt is confirmed, the money will be transferred to the seller's Alipay account.

If the buyer is unwilling to confirm the receipt and the seller is in a hurry to collect the money, you can try to communicate with the buyer to see if you can confirm the receipt, or you can ask the customer service for help and ask the customer service to urge it.
