to close down
🏚️ 倒 (fall/topple) + 闭 (close) = topple-and-shut, i.e. go bust
倒 means to fall over or collapse; 闭 means to close or shut. Together: a business that has toppled and shut its doors — bankruptcy. Compare 关闭 (guānbì, to close) where 关 is a neutral close vs. 倒 which adds the collapse nuance.
倒 — person radical 亻 + 到 (to arrive)
倒 is a semantic-phonetic compound: the person radical 亻 gives meaning (an action done by/to a person), while 到 supplies the sound 'dào'. Originally meaning 'to fall over' (a person toppling), it extended to 'invert, upside down, pour out', as when something falls and spills.
闭 — door 門 + talent 才
Originally written 閉, showing a door 門 with a bar or bolt inside (the 才 component depicts the latch, not the modern meaning 'talent'). The character pictures a door barred shut, giving the meaning 'to close' or 'shut'. The simplified form 闭 keeps the same structure with the reduced door radical 门.
