After listening to Chen Yuan's account, I said, "Indeed, it's unique.

　　The Second Machinery Factory in Xishan that you mentioned is also nearby and has been abandoned for many years.

　　But I can't be sure if this is your true experience, and the story itself is a bit strange."

　　He asked, "What's strange about it?"

　　"In the beginning, you said that your mother brought you here, so your mother must have been working at the Second Machinery Factory in Xishan, right? I don't believe any mother would let her child face the execution scene directly without knowing anything about it, right?"

　　"No, she knew."
