The reason for the application is that the money-saving card is useless and you don't buy anything. When you want to buy something, you can apply for a savings card. Then, fill in the mobile phone number, and you save the screenshot order to save money. Finally, submit a refund application. There will be a prompt when the refund is successful. Not bad.
