What were your experiences of being cheated when you first entered the society, and what lessons did you learn?

I moved with my parents to work in other places since I was a child. When I graduated from junior high school, I went back to my hometown to visit my relatives alone. On the way, I had to transfer several cars. At a station halfway, while waiting for the bus in the waiting room, a man with a local accent in his thirties came up to me and asked me the time. After I looked at my watch and told him, I felt that this man was carrying coals to Newcastle. There must be a big clock in the station. I pointed to the clock again. The man just glanced at it and sat down next to me. Then he asked me where to take the bus. After I told him, he said that he also took this bus with me. About forty minutes later, he chatted with me, asking questions about this and that. At that time, he told him when he was away from home for the first time. Later, a young man in his twenties came and sat opposite us. The man who came first seemed curious about everyone, so he asked where the young man was going. The young man said that he didn't understand the local dialect. The one who came first asked me if I could understand Mandarin, so I told him that the man could listen. Then the one who came first asked me to ask the young man in Mandarin where he was from and where he was going. Although I didn't want to, I asked him for him, and then I worked as an interpreter for them. The young man said that he was from another province and came to do the local copper coin antique business. At some point, the person who came first was going to do business with the young man, and asked me to help them translate and find a quiet place to trade. After that, he gave me a few percent and then gave me a cigarette, but I handed the cigarette he gave me to the young man casually, and then I said that you asked someone else to go to my bus. The first one gave me another cigarette. I was afraid that he would see that I was aware and lit it in his hand and didn't smoke it. I think the time was ten minutes short, so I picked up my trip and went to the ticket gate. Just two steps later, the man grabbed my travel bag from behind. At that time, I punched him in the back, and the man didn't prevent me from falling down.
