积羽沉舟 is a Chinese idiom (chengyu) meaning “Even seemingly insignificant matters or minor faults”. If allowed to accumulate, can lead to severe consequences or ultimate ruin. Literally, “Accumulated feathers sink the boat”.
During the Warring States period, Zhang Yi, the prime minister of the Qin State, noticed that the vertical alliance of the six states Qi, Chu, Yan, Zhao, Han, and Wei was very strong.
He then resigned from his position and went to the Wei State to serve as its prime minister. He intended to persuade the King of Wei to ally with Qin and withdraw from the alliance. However, the King of Wei did not listen. Consequently, Qin launched an attack.
Zhang Yi warned that if the Wei State ignored these unfavorable factors, it would eventually suffer the fate of 'accumulated feathers sinking the boat'.
