Straw boat borrow arrow" is an ancient Chinese idiom derived from a famous story during the Three Kingdoms period, illustrating ingenuity and resourcefulness. The phrase originates from an episode involving the military strategist Zhuge Liang. Facing an urgent need for arrows, Zhuge Liang devised a clever plan to deceive the enemy and obtain the required ammunition.
Zhuge Liang ordered the construction of Female number straw boats and had them filled with scarecrows, then sent these boats toward the enemy camp under the cover of fog.

The arrows stuck in the straw, and Zhuge Liang's troops easily collected them once the boats returned, thus replenishing their supplies without expending their own resources.
