My mother was crazy about those electrotherapy beds before. Every day, she queues up to take the electric chair to sleep in the electrotherapy bed, and even plans to use her pension to buy an electrotherapy bed. Father and uncle tried to persuade her many times, but it was useless. Since one of my cousins bought an electric bed, my mother wants it even more. I decided to have a deep talk with my mother, but I was afraid it would be useless, so I thought of a way. When I came home this summer vacation, I asked my mother how she was recently, and then my mother talked about the electrotherapy bed. She also told me that one of my cousins bought an electrotherapy bed and slept at home every day. So I laughed. I started my plan. I leaned back on the sofa, holding my mobile phone, looked at my mother and said, Mom, you know, one of my classmates is an electrotherapy bed and took me to visit his factory, which is those beds made of plastic. I asked him if these beds were really useful, and he said he didn't need them at home anyway. Moreover, his family earns hundreds of millions of dollars by selling electrotherapy beds every year, and he bought tens of millions of villas and several Mercedes-Benz BMWs at home ... Then I asked him, isn't this bed imported from South Korea? This is made in Shanghai. Why is there an import certificate? My classmate told me that after it is done in Shanghai, it will be shipped to South Korea, and after passing through the customs, the certificate can be sent to the merchants. The cost of the electrotherapy bed was less than that of 200 yuan, but it was sold to 1.6 million. What a windfall! After listening to this, my mother suddenly realized that these people are really making money! Never sleep in an electrotherapy bed again! Liar! I smiled, hiding my merits and fame.
