All the past is a preface. Yun Fan braved the wind and waves: It means that once things happen, they become the past. Don't dwell on the past, but grasp the present and face the future. The "preface" is written in front of the article, not the text, nor is it an important part of the article. Everything in the past is a preface, an understatement of the past. The past not only represents losses, but also includes gains. Whether it's gain or loss, good or bad, it's all over.
All the past is a preface.
Love everyone, trust a few, and live up to no one.
I wasted time, and time wasted me.
In the gloomy days, don't let the cold fate secretly rejoice;
Since fate has come to humiliate us; You should take revenge calmly.
Smart people will never sit down and lament for failure. They must look optimistically for ways to save failure.
