紙上談兵
紙上談兵
戰國時，趙國名將趙奢的兒子趙括，喜歡看兵書，並且喜愛討論軍事戰術。
他把兵書背得滾瓜爛熟，談起打仗來頭頭是道，好像他的父親都不是他的對手。
當秦國進軍攻擊趙國的時候，趙王派趙括率領四十萬大軍去抵抗。
由於他只知道死讀書本而不會在實際中靈活運用，最後指揮失策，以致全軍覆滅，他自己也中箭身亡。
最後人們根據這一歷史故事，把死讀書本，沒有實際經驗，只會誇誇其談稱為“紙上談兵”。
In the Warring States Period (戰國), the State of Zhao (趙國) had a famous general called Zhao She, whose son, Zhao Kuo, was very fond of reading books on military science and discussing strategy.
He could learn military texts by heart, and when discussing warfare he spoke so clearly and logically that it seemed that even his father was not his match.
When the State of Qin attacked the State of Zhao, the ruler of Zhao ordered Zhao Kuo to lead 400,000 men to resist the attack.
But since Zhao Kuo had no practical experience of battle, he was defeated and lost his life.
Later people used this idiom to describe those who are good only at theorizing, and lack practical experience.
