类似支付宝的花呗,各人额度不同,有帐期,比如你额度是400块,那么可以先不用自己的钱,用这个额度去买。然后指定还款日之前,不收利息。
Similar to Alipay's Huabei, each person has a different credit limit and a payment period. For example, if your credit limit is 400 yuan, you can use this credit limit to buy without using your own money. Then no interest will be charged before the specified repayment date.
