Sherlock Holmes' famous words are as follows:

1. You can't reason without any evidence. In that case, you can only go astray.

2. Everything in the world has been done by predecessors, and there is nothing new.

3. It is wrong to confuse strangeness with mystery, but the most common crime is often the most mysterious, because it has no strangeness as the basis for reasoning and judgment.

4. What is not noticed by people is not an obstacle, but a clue. When solving this kind of problem, we mainly use reasoning method to push back layer by layer.

5. Don't let a person's appearance affect your judgment, which is the most important thing. Emotion will affect reason.

6. We must go deep into life. Only in this way can we get novel effects and unusual cooperation, which is more exciting than any imagination.

7. Generally speaking, the stranger things are, the more common the inside story is when the truth comes out. And those very ordinary cases are confusing.

8. Life is very boring. My whole life is trying not to waste my time in mediocrity. These small cases have made my wish come true.

9. Unusual phenomena can always give people some clues, while cases with no features are difficult to solve.

1. How important it is to imagine! Imagine what has happened and do it according to the idea, and maybe you can find the result.

11. In detective work, the most important thing is to be able to distinguish between priorities from complicated facts. Otherwise, instead of concentrating, your spirit will be distracted.
