Alibaba's delivery is slow. As an e-commerce platform, Alibaba sells a wide variety of goods and a large number of orders. It also needs to consider multiple links such as inventory and logistics, which leads to slow delivery. In addition, to ensure product quality and customer satisfaction, Alibaba will also conduct quality inspections and reviews on sellers' goods, which will also extend delivery time. However, in order to improve customers' shopping experience and satisfaction, Alibaba is also constantly upgrading its logistics system and increasing investment and efforts. In addition, Alibaba also allows sellers to use their own logistics channels for delivery. I believe that in the future, delivery speed will continue to increase to better meet customer needs.
