Why is the postal express parcel delayed?

Question 1: It can be understood this way. Actually, it's like this, because when you bought this thing, all the courier companies were on holiday, or it was about to be on holiday, so you couldn't mail your things, so you switched to EMS, because EMS has no holidays all year round. If you choose EMS and the seller says that the courier company switched to the postal parcel system, it's because the seller didn't send you EMS at all, because EMS is more expensive. The seller couldn't make the difference, so he gave it to Shentong, Tong Yuan, Zhongtong or Daily Express. Because these courier companies have low prices, and it is time for holidays, they have to transfer to postal services. As I said just now, EMS is expensive, so I switched to postal parcels, because postal parcels are only a little more than one yuan per kilogram.

Question 2. Because postal parcels are inherently slow, coupled with holidays, and now EMS postal parcels use the same network and the same processing center, coupled with the Chinese New Year, the postal goods are seriously overstocked and the operational capacity is greatly weakened. So it still needs to wait for a few days, which is also helpless.
