1. Before all the clues are possessed, a hypothetical conclusion is the most taboo, which will lead to errors in judgment.

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. things that are not noticed by people are not obstacles, but clues. 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. For a real theorist, if someone points out one aspect of a fact, he can infer not only all aspects of the fact, but also all the consequences that will result from it. Just as Ju Weiye can accurately describe a complete animal from a bone after careful thinking. An observer, having thoroughly understood one link in a series of events, should be able to accurately catch all other links. We haven't reached the point where we can reach a conclusion as long as we master rationality. The problem can only be solved through research. If you want to solve the problem only by perception, you will definitely fail in the end. However, to bring this talent into full play, the reasoner must be good at using all the facts he has mastered. This means that the reasoner should master profound knowledge.

11. once you have eliminated all the impossible facts, what remains, no matter how incredible, is the truth.

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

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

14. once or twice, I deeply realized that the harm I caused by catching criminals was more serious than the crime itself. I have learned prudence now. I prefer to cheat the law to my conscience.

15. First of all, all the impossible conclusions should be ruled out, and the rest, no matter how bizarre and unbelievable, must be irrefutable facts. Perhaps there are several explanations left, and if so, we must confirm them one by one, until at last there is only one explanation with sufficient evidence.

16. when all other possibilities are eliminated, there is one left, no matter how impossible, it is the truth.

17. In the eyes of a great man, nothing is trivial.

18. Human beings are small, and work is everything.

19. If the journey of my life ends tonight, I can also die with a clear conscience. Because of my existence, the air in London is fresh. In more than 1 cases I have handled, I believe that I have never used my strength in the wrong place.

2. If I can guarantee to destroy you, then, for the benefit of society, even if I die with you, I am willing.

21. Since it is morally justified, all I have to consider is personal risk. If a lady is in urgent need of help, a gentleman should not think too much about personal safety.

22. Watson, I have never been in love. However, if I have been in love, if the woman I love is in such a terrible situation, I may do it like our lawless lion hunter. Nobody knows.

23. With time, nothing is invincible.

24. Brother Watson, this is really a fixed moment in a changeable era. There will be an easterly wind. This kind of wind has never been blown in Britain. This wind will be very cold and fierce, Watson. Many of us may wither when this gust of wind blows. But this is still the wind of God. After the storm has passed, a purer, better and stronger country will stand in the sun.

25. Fools are stupid, but there are more stupid people applauding them.

26. My mind is everything to me, and my body is just an attachment.

27. If I can rid the society of the scourge of moriarty, then I would rather end my detective career. I can say that I haven't wasted my life at all. If my life journey ends today, I can die with a clear conscience. For me, there is nothing more satisfying than this ending.

28. You are watching, and I am observing. There is a clear difference.

29. it would be strange if you know all the details of a thousand cases and can't solve the 11st case.

3. You said we walked around the sun, but even if we walked around the moon, it wouldn't affect me and my work.

31. Modesty and pride run counter to the facts.

33. Watson not only looks with his eyes, but also calls it observation. Seeing is very different from observing.

34. The so-called event can be easily solved as long as there is something that cannot be solved. It is the crime that looks ordinary and featureless that is really tricky.

35. People should not beat around the bush on the theory of explaining the facts, but should cooperate with the explanation of the theory and slowly solve the truth.

36. No matter how flawless the crime is, as long as it is committed by people, there is no reason why it cannot be solved.

37. The air in London is fresh because of my presence.
