Origin Story
战国时期，楚国有个乘船过江的人，不小心把剑掉入江中。他立刻在掉剑处船舷上刻了个记号，心想船靠岸后，从记号处下水就能找到剑。船靠岸后，他果然在记号处下水寻找，却怎么也找不到剑。原来，船在行驶过程中，剑的位置早已改变，而他却固执地按原来的记号寻找，岂能找到？
During the Warring States period in China, a man from Chu dropped his sword into a river. He immediately marked the spot on the boat's side where the sword had fallen, thinking he could find it there after the boat docked. After docking, he did search at the marked spot, but could not find his sword. The reason was that the sword's position had changed while the boat was moving; he stubbornly searched at the original mark, doomed to failure.
Usage
常用作比喻，形容很多人盲目跟风，争先恐后地追逐某种事物。
