JD.COM is a platform for large-scale shopping. When a buyer submits an order on the platform, the platform will show that the number is real, so the platform can see the number of buyers' reservations and it will be displayed on the big platform, so this data is generally true.
JD.COM merchants set up reservation activities in the background, and users get the purchase qualification by participating in the reservation. After the appointment is over, the snap-up begins, and the user can directly place an order to buy.
