The epidemic situation is caused by the following reasons. 1, the traffic may be due to the rush hour, such as traffic jam, which leads to the delay in updating the express information, so our express delivery has been stopped at one place.

Another reason for encountering natural disasters is that it is possible that your express caught fire during transportation. The reason is that there is too much backlog of express delivery, the weather is dry and the express delivery information is not updated. 3, do not deliver goods sometimes encounter special festivals, a large number of people place orders, resulting in merchants can not deliver goods to themselves in time, resulting in a backlog of goods, and may also form a courier that has been parked in one place. 4, the courier staff is not enough, for example, near the end of the year, the volume of express delivery has increased greatly, but the courier companies are very embarrassed. Many companies have encountered difficulties in recruiting express delivery staff, so their express delivery may become "slow" or not.
