Is the total amount of the group set written per capita or all?

Per capita. For the time being, it is not supported to directly fill in the per capita amount for quota collection. You can enter the total amount directly, and the system will distribute it evenly according to the total amount and the number of people. The advantage of group payment is that if group members fail to pay for 24 hours, group payment will send a system reminder to friends who have not paid for more than 24 hours, so that the payee can avoid the embarrassment of taking the initiative to remind.
