What does 关 mean?
关 (guān) is the everyday verb for shutting something or switching something off. Three core uses cover most cases: physically close — 关门 (close the door), 关窗户 (close the window); turn off electronics — 关灯 (turn off the light), 关电视 (turn off the TV), 关机 (power off / turn off a phone); and shut a business or operation — 商店关了 (the shop has closed). It also appears as part of broader compounds like 关心 (care about — see separate entry), 关系 (relationship), and 关于 (about / regarding).
Two notes for English speakers: first, Chinese doesn't distinguish 'close' (door)
Character breakdown
to close; to shut; pass / barrier (the simplified form replaced the older 關 showing a gate with a bar across it)
Memory hook: Picture a gate with the crossbar dropped in: 关 — closed, shut, the path is barred.
