How is qq group buying BYD f0? Is it really 499 yuan?

This is an activity, just like a lottery. You are not eligible to spend 499 yuan on this car until you get it. In other words, if you draw, you have to pay 499 yuan to win the prize. But this activity is not a lottery, but a grab, which is what they call a second kill. Who grabs this qualification (see who clicks the mouse quickly); Whoever can buy a car will not have to pay for it. There is a car for the whole activity. . .
