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

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

3. 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.

4. With time, nothing is invincible.

5. 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.
