Multi-system loading method and device, equipment and storage medium

The invention discloses a multi-system loading method and device, equipment and a storage medium, and belongs to the technical field of computers. The method is applied to terminal equipment comprising a main system and at least one subsystem, and comprises the following steps: acquiring a subscription subsystem identifier of a current login user; determining subsystem information displayed in a main interface of the main system based on the subscription subsystem identifier; displaying a main interface, wherein the main interface comprises subsystem information; determining a to-be-loaded subsystem identifier based on the operation acting on the main interface; storing the to-be-loaded subsystem identifier into a preset object; and loading a subsystem corresponding to the to-be-loaded subsystem identifier. According to the method and the device, the problems that a plurality of different bidding and tendering systems are operated in the same equipment, a user needs to register in each bidding and tendering s
