The lightning box is a liar. I didn't even know, so I automatically deducted the money and said I bought something at 28.45 in the lightning box.
It's time for you to open a shopping app like Pinduoduo with a lightning box. After shopping in Pinduoduo, the lightning box will show how much you bought. After receiving the goods, the lightning box will give you the corresponding lightning coins. For example, your Pinduoduo order of 28.45 yuan will give you a lightning coin worth 2.88 yuan after it is received and commented by the lightning box. You can convert it into cash at the balance and withdraw it to WeChat when 30 yuan is full. This is me.
