The main reason is that there is a possibility of sudden orders, which will extend the delivery time.

The traffic on Douyin is explosive, and there is a high possibility of sudden orders, so when doing Douyin live streaming, the store's delivery time will be set to the longest time, otherwise the money will be deducted for slow delivery. If Douyin has a sudden order, the factory may not be able to produce in time. Under this premise, the delivery speed cannot be fast.
