According to the low-income guarantee method, 15 points are deducted per day, 15*15=225. After one deduction of 225-15=210 points. For the next 15 days, the score will be 0+14*15=210 points. This is the normal method, requiring 15 points to be deducted on the same day, resulting in 0 points. If you do not deduct, then 210-15=195. According to the current trend, you will only eat once a month. If you deduct on that day, then you can eat twice a month.
