Tips

history
From Li Bai's (李白) Tang-dynasty masterpiece 《蜀道难》 ('The Road to Shu Is Hard'): 剑阁峥嵘而崔嵬,一夫当关,万夫莫开 ('Jian Pavilion towers tall and steep - one man guards the pass, ten thousand cannot break through'). The line described the Sichuan road's near-impassable mountain passes.
usage
Used both literally (military terrain, fortified positions) and figuratively (any single critical point that controls a whole system - a database, a doorway, a bottleneck process). Often shortened to just the first half: 一夫当关.
