JD.com's one-hour door-to-door delivery is JD.com's same-city express delivery. After receiving the order, the courier goes directly to the customer to pick up the parcel, checks it, packs it, seals it, takes a photo and uploads it to the platform, and then delivers it directly to the recipient at the fastest speed. There is no link in between, which is also the outstanding part of JD.com's high express delivery efficiency.
