My design is a classroom that can be disassembled, folded, and assembled. It is powered by solar panels on the roof. Pre-stored information about "child education, agricultural production, and work information" is available for playback in the system. Get the information you need with a foldable table and chairs.
The design is simple to assemble, simple to operate, does not require instructions, does not require special tools, can be installed by hand, and can be folded for convenient transportation after use. The device can also be used as a charging base station to charge people's small devices and facilitate people's lives.
