The Convention is a virtual activity, involving various activities and services, such as online seminars, speeches, social activities and so on. Although these activities do not need the support of logistics, the organization and operation need the support of logistics. For example, organizers need to transport meeting materials and equipment from one place to another, or transport the luggage of participants from airports or stations to hotels. In addition, there are product exhibitions or sales activities, and goods need to be transported from manufacturers or warehouses to the event site.
