Everyone has their own lucky number, and the lucky number is different every day. In the APP, you can generate weekly lucky numbers at one time, so you no longer need to choose a lucky number every day. The lucky number for one month is automatically generated. You can choose one of the lucky numbers of the week as your lucky number for this week, or you can manually select the lucky number for this week. You can add the lucky number you like to the optional , so that you dont forget or need to generate again, just check it directly in the record.
