Buy something for others in Tmall supermarket, and others can see it.

Because someone else's mobile phone will display a courier, because after the courier is sent, it will give the recipient's mobile phone number and send a text message, so you can see it when you buy it. If it's for someone else, just fill in someone else's phone number, and someone else's mobile phone will receive a text message, so that others can know what you bought her, but he can't know who bought the courier.
