You can participate in this event by swiping your card for more than 100 yuan. The rule of the event is that the last 8 is the winner. The reward for an 8 is three times the points for this purchase. The highest reward is 6 8s, which is the last 6 If the digits are all 8, then the reward is 4888 yuan of free spending. Yours is three 8s, and I don’t know what the specific reward is. But this is real and not a lie. I've been hit by it myself, haha. Unfortunately, I am not as lucky as you. I only have an 8. At that time, I didn’t know whether it was real or fake, so I called 95508 to ask the customer service. You can do this. You call 95508, press key 1 to select Chinese, and press key 0 twice to be directly connected to the manual. Then you can directly ask customer service. They will give you specific answers. Hope it helps.
