Actually not, it’s just a marketing strategy. Before doing the calculation, I first ask you to send a screenshot to Moments, saying that the calculation is accurate, and sending a screenshot of the chat. When people in your circle of friends see it, they will think you have calculated it and said it is very accurate, so everyone will try it. I think it must be because I trust you to post in the circle of friends. In fact, most of them have not experienced it yet, so they ask you to post some confirming words, deceive acquaintances, and use acquaintance psychology to attract other people. A month later, you will find that he will also sell other things in Moments.
