This is a true story about my friend.

He made a special trip back to Xijing from a distant place and dragged me to talk about five days and five nights. First at the tavern in Zhongshan Gate, and then at my house, I began to think that he was telling jokes, or that I heard the jokes on him on purpose, but as I listened, I couldn't help but ask him, "Is this all true?"

He said, "We've known each other for thirty years, did I lie to you?"

I was silent, and continued to listen to him, and gradually from disbelief to belief, and the more I listened, the more energetic I became, until I felt that it was time to sleep, and we fell into bed with opposite feet, and I still could not sleep.

I said, "Go on."

But he came to sleepiness and said, "Tomorrow, I need to get some sleep."

This conversation lasted for five days, and I sometimes couldn't help but cast a puzzled look at him, and my attitude changed from interest to shock, if everything he said was true, my three views would collapse from now on! Everything that has been seen, experienced, and even about to happen in these decades will become unreal.

I couldn't help but ask him again to confirm: "Is all this true?"

He extinguished the cigarette in his hand and said lightly, "Others may not believe me, but you should believe me."

I took a deep breath, tried to calm down, and said, "Can I write it down?"

He said, "Write it, it's time to know the truth."

Until this moment I put pen to paper, our conversation continued, and tomorrow we will meet in a secluded teahouse, where he will tell me the final story.

My friend's name is Li Bing, and I went to the same school as him for the children of factories and mines, and I was a classmate in primary and junior high school.

I'm still alone, and he's already a man with a wife and children. Zhang Ailing said: "When a man reaches middle age, he often feels lonely, because when he opens his eyes, he is surrounded by people who want to rely on him, but there is no one he can rely on." ”

He may be in such a state, in my eyes, he will live this life in an ordinary way, like most of my friends, but all the changes have to start with that unbelievable change.

I am constantly recalling his story, interspersing many fragments together, trying to sort out the clues and write them down completely. After all, I am not an eyewitness to the incident, and there are many things that he must tell in detail, but this is not the point, the point is that at this time, I feel deeply responsible and obliged to tell the ultimate truth.

Where to start? The first thread that is inextricably linked is that strange change.
