If the online reservation is full, you can't make an appointment for this time. You can make an appointment for the next time. Generally 14 days in advance, and the number is zero.

Online booking only accounts for half of the day's registration. Half of the numbers are registered in the window of the day, so we have to queue up at five o'clock, and we can almost hang up the numbers. Someone said before that if you go to the queue at 7 o'clock, you won't be able to hang up the number.
