Transferring privately is forbidden.
If you transfer money to your friend in the Taogo's account privately. Due to the Alipay's policy, this account would be refreshed after one year. You can't receive the refunds before the account refreshing. The refunds would return to the Alipay's account of the seller after one year. And you need to offer the screenshot of your friend's account number in that time. (The screenshot includes the Alipay's payment account number, date/time, the payment amount, transferring number and the note information.) Sending the screenshot to Taogo's client service mailbox, it would return the refunds to the seller.
