Trading on ebay and Alipay with paypal is slightly different.

Alipay temporarily collects money on the platform, and when the customer confirms the receipt, the money will be transferred to the seller's account.

Paypal is the paypal account of the direct payer. If the other party fails to deliver the goods or the goods are not satisfied, it can initiate a dispute within 45 days to safeguard its own interests. Anyway, paypal is very reassuring, and they protect buyers very well. Ask other questions.
