方向 (fāngxiàng) is a noun meaning 'direction, orientation' — it refers to a direction as an abstract concept or a specific route (e.g., 走错了方向). Do not confuse it with 向 (xiàng), a preposition meaning 'towards' that indicates the target of movement or an action (e.g., 向南走). Use 方向 to talk about which way something is or should go, and 向 to describe the direction of a movement or the recipient of an action.
