What does it mean for girls to send friends from day 10 to day2?

This is just the serial number of the days she completed a task.

Day, English translation means a day and a period, and day0 means 0 days as its name implies. Day0, 0 days, this is very common, okay? Netizens who don't understand the deep meaning will definitely have questions. In fact, this is the old driver punching in, which is the number of days of abstinence. Day0 is the beginning of abstinence, and Day 1 is abstinence 1 day, but the most news I have seen all the time is day0, as well as day 1, day2, day3 and even the n power of day, which shows that lusir can't quit at all and has to sign in with day0 every day.
