2.**Using their delivery system to distribute the products.**

Disaster relief is about 80% of logistics it would follow [7]. As relief supplies are very likely to be distributed in challenging situations while in presence of compromised infrastructure, destroyed or blocked roads and limited manpower and resources, a widely-covered supply chain network (including the supplier partnerships, warehousing, and transportation systems and personnel resources) with well-established logistics mandates and information system will save a lot of time in delivery. Many e-commerce platforms have their own self-supporting logistics service system like Amazon.com and JD.com [15], laying the groundwork for a highly efficient distribution network. To combat the pandemic COVID-19, the Hubei Provincial Government cooperated with the JD logistics to manage the disaster relief supply chains. By utilizing their supplier resources and logistics system, JD logistics has distributed over 2000 tons of relief supplies to Wuhan and its neighboring areas in the first twenty days since Wuhan's lockdown. Without the support of JD logistics, it would be extremely difficult for the local hospitals and community to acquire the whole and complete medical supplies and living necessities that were needed, and deliver them to the demand point in such a timely and cost-effective manner.

Using the e-commerce platform's delivery system is beneficial for the integration of humanitarian logistics activities. While there may involve thousands of converging supply chains in disaster relief operations, lack of coordination is the chief cause of material, manpower, and information convergence. In contrast, given that the e-commerce platforms provide systematic logistics services through bridging the real-time demand with their partner suppliers' capacity, sharing their logistics services can reduce the overall logistics cost and improve the efficiency of rescue and relief operations.
