After each group met on the train, they all talked about Deqin Emerald in the same way: they were the bosses. If they meet people from the Tourism Bureau at Shanghai Railway Station and put in a good word for their company, they will give everyone a jade coin. At that time, everyone thought that such a big boss had no shelf at all. They also explained how to identify jade and how to look at the cost price, and then said that they met you today and sold it to you at the cost price. At that time, everyone was very grateful to him, and someone really paid for it. When I said it on the train, the routine was the same, only to find that I was cheated.
