Dong Peng frowned again. "The method is good, but there are some small problems hidden in it. For example, if there are some people who are greedy for small benefits and only use it for three days, what if they don't buy it? What if there are any damages to the product or parts within the three days of users using it for free? Then who is the last person in charge?"
"I understand President Dong's worry, but these are the most common things. It's not a big problem. I can answer one or two questions for President Zhou."
Shan Yue drank the remaining half of the cup of tea on the table. "First of all, big data has already developed to an unimaginable level. Anyone who comes to use it for three days for free needs to register in advance and store the information of the users. As long as we stipulate that everyone only has one opportunity to experience it, no one can take advantage of this loophole."
