JD.COM bought food in the US delegation after returning home, Ding Dong bought food, and so on. You can buy it here in Hubei and in any city. As long as you place an order online, logistics will deliver it to your door in person.
In order to facilitate rapid transportation, under normal circumstances, as long as the goods are purchased by themselves, they will be delivered in advance, so that they can be delivered to nearby supermarket outlets as soon as possible, and then they can pick up the goods themselves. This is to prevent others from taking the wrong things.
