Long ago, there was a man from the State of Chu who loved his sword very much. One day, he was sitting in his boat preparing to cross a river, when he accidentally dropped his sword into the water. He immediately made a notch on the side of the boat at the place where his dear sword fell. When he returned close to shore, he re-entered the water just beneath the notch he made, looking for his sword. Naturally, he wasn’t able to find it.
The sword was already gone because the boat and the river were in motion. This idiom is used to describe a person who sticks to rigid rules without considering a changing environment [or describes an action made pointless by changing circumstances].
