Careless supermarket owner

Early in the morning, a man with a wrinkled face and puffy eyes came to the Qiaobei police station to report a crime, and was greeted by a young policeman. 　　"Here's the thing," the man said, "I found out that I seem to have been duped by a con man." 　　The young policeman, holding his pen, interrupted him politely and said, "Excuse me, what is your name?" 　　"My name is Yongpyong." 　　"Okay, Yongpyong. You're not from here by accent, are you? Are you from Shandong?" 　　"Yes, my hometown is Shandong, and I came here only a month ago." 　　"You just said you were cheated, when was it?" 　　"About a month ago, I don't remember very well, maybe it was longer." 　　"Why didn't you come to report it until now?" 　　"To be honest, I wasn't sure if I was really fooled, I kept waiting for him to show up again, but after so long, I didn't hear anything from him. I wonder if I've really been cheated?" 　　"Please tell me more about that." 　　"You know, I'm a foreigner, a month ago, opened a small supermarket in West Street. I have no relatives here, not even a friend. Just the day after I opened, early in the morning, just after I opened the door, a tall, thin man walked into the store ......" "Was it a man?" 　　"Yes, he took two cigarettes and a case of high-grade white wine. When he paid the bill, he stared at my face for a while and asked, 'Are you Yong Ping?' You can imagine how surprised I was, to meet someone who knew me a thousand miles from home. I looked at him carefully and felt unfamiliar, but it was déjà vu. What a damned memory I have. Then he said: 'I am also from Shandong, have you forgotten? Yongping, I'm Jianguo.' Only then did I dimly remember that there might indeed be such a person." 　　"As far as I know, in any city, you can find hundreds of people named 'Jianguo'. Do you recognize him or not?" 　　"That's exactly what I was wondering. But you see, he knows my hometown, and he can call my name exactly, so he must know me. But I really don't know if I know him anymore. My memory is too bad ......" "And then?" 　　"Later, we had a nice chat, after all, it's a hometown. Finally, he said: 'Yong Ping, if I give you credit, you will not be uneasy with me, right?' How could I be uneasy with him? In this city, he was the only one who knew me. I agreed, I let him take credit for 800 yuan of merchandise, and when he left, I slipped him another 200 yuan." 　　"Why did you do that?" 　　"It's not just to make up a whole number. ...... Jianguo said he would pay me back in a week at most, and then buy me a drink. After he left, I have also been very excited and feel that I am not so alone here. But since then, and I don't know how many weeks have passed, I've never seen him again, and I vaguely feel that I haven't really been fooled?" 　　"It's possible. It's not a new trick to pretend to be an acquaintance, gain trust and then cheat you out of your money. You trust people too easily." 　　"But think about it, I just arrived here a few days ago, there is no one I know, if he is a fraud, how did he know my home, how did he know my name? What reason do I have not to trust him?" 　　"I can tell you are from Shandong by your accent, but how in the world did he know your name? If he is really a liar, we need to figure this out first. Have you made any friends or told anyone your name since you've been here?" 　　"No, I haven't told anyone, and I didn't have any contact with anyone before I opened the supermarket." 　　"Did you lose your ID card?" 　　"The ID card was always in my coat pocket." 　　"What about your train ticket to this city? You know, the train ticket also has your personal information on it." 　　"I came here by car." 　　"That's strange. Well, I've taken a statement, and it's not certain whether he's a fraud or not. I'll let you know right away if there's any progress in this matter. But maybe he's really a friend of yours from back home, so you might want to wait a little longer. So, one last question, Yongping, what is the exact location of your supermarket?" 　　"Mudan West Street, opposite the Pearly Garden Hotel." 　　The police officer was making a statement while repeating, "Hmm? Mudan what is the name of your supermarket?"

　"Yongping Supermarket." The police officer's pen stopped in mid-air and said seriously, "Yongping, I can tell you with certainty that he is a liar."
