Why hasn't Chongqing Yucai school uniform been received for more than ten days?

Supply chain problem, logistics problem.

1. supply chain problem: the production and transportation of school uniforms need to go through multiple links and multiple suppliers. Any delay in any link will affect the delivery time of the whole order. For example, the fabric supplier may not be able to deliver the goods on time, or the transportation company may delay the delivery.

2. Logistics problem: the student's address is inaccurate or the recipient can't be contacted, so the school uniform can't be delivered in time. In addition, if there are unexpected situations during transportation, such as bad weather or traffic jam, it will also affect the delivery time.
