The chances of buying U from the shield seller are quite high, right? Last month I bought 20 with a bank card and there were no issues.

I want to ask the seniors how they recharge U. In a day, they can instantly recharge thousands or even tens of thousands, but I can't find a channel at all. I really want to know how to do it. Using regular WeChat or Alipay, after transferring ten thousand, when I add friends to continue recharging, I start getting risk warnings and can't transfer anymore. It's like having money but not being able to spend it. The next day, they even restrict you. It's so hard to recharge. Please guide me, esteemed seniors. If I achieve something in the future, I will surely repay you generously! (holding fist) (thank you)
