Abstract: A modular flooring includes a plurality of floorings and a plurality of floor connectors. Each of the floorings has at least two opposite sides respectively formed with a hidden engaged hole which is a recessed structure. When the floorings are laid adjacent to each other and the corresponding hidden engaged holes of each two of the floorings are aligned with each other, each of the floor connectors is respectively inserted into the corresponding hidden engaged holes, so that the floorings adjacent to each other can be combined mutually. As a result, the assembling convenience and the flexibility of the modular flooring are increased.
