The word **铺盖 (pūgai)** is a compound word formed by combining two semantically related characters: **铺 (pū)**, meaning "to spread out" (often referring to a mattress or bedding mat), and **盖 (gài)**, meaning "to cover" (often referring to a quilt or blanket). Together, they create a new meaning through juxtaposition, where the two items—the thing spread beneath and the thing laid on top—represent the complete set of **bedding**. Over time, the term has also gained a figurative meaning, referring to one's **luggage** or **belongings**, especially when moving, as bedding is a core and bulky necessity.
