A fence module includes fence module units each having a first pair of extensions, a second pair of extensions opposite to the first pair of extensions, and a third pair of extensions adapted to extend into a surface to stand the fence module unit upright. Each of the first pair of extensions has a through hole and each of the second pair of extensions has a cone-headed projection to correspond to one of the through holes of the first pair of extensions of an adjacent fence module unit so that connection of the cone-headed projection and the corresponding through hole is able to assemble a fence that is able to adapt to terrain.
