纸上谈兵
纸上谈兵
战国时，赵国名将赵奢的儿子赵括，喜欢看兵书，并且喜爱讨论军事战术。
他把兵书背得滚瓜烂熟，谈起打仗来头头是道，好像他的父亲都不是他的对手。
当秦国攻进军攻击赵国的时候，赵王派赵括率领四十万大军去抵抗。
由于他只知道死读书本而不会在实际中灵活运用，最后指挥失策，以致全军复灭，他自己也中箭身亡。
最后人们根据这一历史故事，把死读书本，没有实际经验，只会夸其谈称为“纸上谈兵”。
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.
