A window covering includes a headrail, a bottom rail, a shading member, two pulley assemblies, and a cord. The shading member is between the headrail and the bottom rail. The pulley assemblies are received in the headrail, each of which has a frame and a pulley. The frame has an opening, and the pulley is connected to the frame. The cord is a woven Y-shaped cord, having a single control section and two lift sections. The cord runs over the pulleys of the pulley assemblies, the single control section extends out of the headrail to be operated by a user, and the lift sections extend out of the frames via the openings respectively to connect to the bottom rail through the shading member.
