to win a war with words
In the Warring States Period (战国), the State of Zhao (赵国) had a famous general called Zhao She, whose son, Zhao Kuo, was very fond of reading books on military science and discussing strategy.
战国时，赵国名将赵奢 (shē) 的儿子赵括，喜欢看兵书，并且喜爱讨论军事战术。
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.
Later people used this idiom to describe those who are good only at theorizing, and lack practical experience.
英语中“纸上谈兵”的表达方式相对比较直白，通常可以说“to win a war with words”，在经典影片《乱世佳人》中，战争爆发前夕，当南方贵族们在夸夸其谈讨论如何作战时，白瑞德就说道：
“I think it’s hard winning a war with words.”（“我认为纸上谈兵没什么作用。”）
