A: Every package follows a highly optimized and secure logistics path to ensure fast and reliable delivery. It begins at my warehouse in Hong Kong, where it is prepared for shipment before being transferred to Cainiao Global Express' logistics hub in Mainland China, marking the official start of the shipping process. From there, the package moves through Cainiao's high-efficiency logistics network, ensuring continuous monitoring and rapid transit to its destination country. Once it arrives, it is either handed over to a local Cainiao subsidiary or entrusted to a major national carrier for smooth final delivery. This process guarantees secure, fast, and well-tracked shipping, providing the same level of efficiency as major global retailers.
