They have no practical experience(白面書生)
During the period of the Northern and Southern Dynasties of China, the Liu Song Kingdom had a famous general whose name was (Shen Qingzhi).
There is a story about him in history books.
One day, in a meeting, the king said to all the ministers.
I am going to send troops to attack the Northern Wei Kingdom.
He said when he heard it.
This is a bad idea.
We have had two previous experiences, but we all failed. We should think more about it.
Said the king.
Our previous two failures were due to problems with the generals at the time.
Now this season is summer, and summer is good for water wars. This is exactly what we are good at.
The Northern Wei Kingdom is better at land warfare, so I think this is a good time.
At this time, two administrative officials who attended the meeting said.
We agree with the king.
He said to the king.
If you want a good harvest, you have to ask an experienced farmer for his opinion. If you want to make good fabrics, you have to ask an experienced woman for advice.
War is very professional. If you listen to the opinions of these two people who can only recite knowledge from books but have no actual war experience, I think this matter will definitely fail.
The king laughed after hearing this.
This idiom is used to describe a person who can only recite knowledge from books without practical experience
Dear friend, what inspiration or thoughts did you have after hearing this story.
If you were a king, whose opinion would you listen to? How would you combine your knowledge with practical experience?
I hope this story will give you some new gains.
白面書生(They have no practical experience)
在中國的南北王朝時代，劉宋王國有一個著名的將軍，他的名字叫做(沈慶之)。
歷史書上記載了一個他的故事。
有一天，在一場會議中，國王對所有的大臣說。
我準備要出兵，攻打北魏王國。
他聽到後就說。
這是一個不好的主意。
我們之前已經有兩次的經驗，但是都失敗了。我們應該多加考慮。
國王說。
我們之前兩次的失敗是因為當時的將領有問題。
現在這個季節是夏天，夏天有利於水戰。這正是我們所擅長的。
北魏王國比較善於陸戰，所以我認為這是一個好時機。
這時候，有兩個參加會議的政務官說。
我們贊同國王的看法。
他對國王說。
如果你要有好收成，你就要問一個有經驗的農夫的意見。如果你要織出好的布料，你就要問一個有經驗的婦女的意見。
戰爭很專業，如果聽取這兩個只會背誦書本上的知識而沒有實際戰爭經驗的人的意見，我認為這件事情一定會失敗。
國王聽了後大笑。
這句成語被用來形容一個人只會背誦書本上的知識而沒有實務經驗
親愛的朋友，你聽完這個故事有怎樣的啟發或有怎樣的想法呢。
你如果是國王，你會聽從誰的意見呢?你如何讓自已的知識與實際經驗相結合呢?
我期待這故事能讓你產生一些新的收穫。
