Internet speed, computer reasons. Why should I open it? I don't advise you to buy a group purchase in JD.COM. I bought it several times and it broke up in discord! The first time: the gorgeous moon cakes bought during the Mid-Autumn Festival were not delivered for 5 or 6 days, and the Mid-Autumn Festival is coming soon, so there is no way to return them! The second time: I bought the order ID 92735403 from the group a few days ago, and I want to go out to play during the eleventh period. I was told that there were no tickets! This is my real experience! I am so angry!
