Comes from the well-known
守株待兔 (shǒu zhū dài tù, “guard the stump waiting for a rabbit”) parable in 《
韩非子·
五蠹》(Han Feizi, Five Vermin), where a farmer abandons his work to stand by the stump where a rabbit once accidentally killed itself.
株守 distills the moral: stubborn passivity in hopes of repeating dumb luck.
