What are the classic quotations in Preface to Mountains and Rivers?

1, once in the Jianghu, the youngest son is old.

2. Just like an abyss. Some people jumped over and went out, while others fell dead without jumping over. And that abyss has a name-Jianghu.

3, the mountains and rivers are not heavy enough, it is very important to meet a bosom friend.

4, Jianghu Yao, wherever you go, there are right and wrong. Tang Chao is a vanity fair, and Jianghu is a field of right and wrong. Some people always don't understand this matter, as if riding around the world with a sword is a great thing, and everyone is chanting when they die.

When I find the real way to return to the world, I will become a person again, like when I was outside, with a good temper, no longer moody and crazy.
