Core Viewpoint - The rapid expansion of Sam's Club's "cloud warehouse" model and its "one-hour express delivery" service has raised concerns about the safety and working conditions of delivery riders, particularly regarding overloading issues [5][20]. Group 1: Expansion of Cloud Warehouses - Sam's Club has opened four new cloud warehouses in various cities, bringing the total number of cloud warehouses close to 500 [5][18]. - The "one-hour express delivery" service relies on a network of cloud warehouses, typically covering a delivery range of 3 to 5 kilometers from the warehouses [8][15]. - The cloud warehouses are designed to serve online orders and are equipped with various storage facilities to accommodate a wide range of products [15][17]. Group 2: Delivery Rider Challenges - Delivery riders face significant pressure to increase their order volume to boost their income, leading to instances of overloading their electric vehicles with heavy goods [6][11]. - The average order weight often exceeds the system's limit of 30 kilograms due to the nature of the products sold, which are typically bulk items [12][11]. - Riders are compensated based on the number of deliveries rather than the weight of the goods, which incentivizes them to take on more orders, exacerbating the overloading issue [12][13]. Group 3: Financial Performance - Walmart China's net sales reached $12.365 billion in the first half of the 2026 fiscal year, reflecting a year-on-year increase of $2.482 billion [19]. - The second quarter saw net sales of $5.786 billion, with a growth rate of 30.8%, and online sales growth reached 39% [19].
