Automatic Deduction Failed

Acheng is a careless office worker. After receiving his monthly salary, he always spends it inexplicably and worries about the bills at the end of the month. Until he accidentally opened Alipay's "Payment Assistant" function - this intelligent management tool will automatically help him choose the most cost-effective payment method based on his balance, Huabei limit, bank card coupons and other conditions. At first he didn't believe it, thinking it was just a "one-click payment" button. Three months later, he was stunned when he received the bill: the water and electricity bills were deducted on time, coupons were automatically used for takeaways, and even credit card repayments missed the peak processing fee. He scratched his head and left a comment in the Alipay settings: "It turns out that you have been helping me save money, but I always thought that you just spent the money for me."
