Once there was a doctor who had an exam in the Army, and he got a very high score, but he thought it was because he was good at that kind of questions, if in other fields, he would not have such a high score. All in all, every profession produces its own leading authority. For example, a mechanic knows very well about the car, but this doctor hardly knows anything about the car reparing thing. Once the mechanic was reparing his car and asked him a question, the mechanic said, there was a deaf people who went to a store to buy nails, and he's gesturing to the boss who did not come up with what he wanted the first time, but the boss took out a nail after this deaf gestured for the second time. what if a blind man should do if he wants to buy a pair of scissors? The doctor said, he should put the fingers into the scissors shape. The mechanic smiled, and said, you are wrong, he should say it out directly!
