Personally, I think there is something wrong with your question. It is oriental culture to drink the wind and cross the valley. Why should it be calculated according to the course of treatment? Besides, have you ever known the valley? Do you know what Bigu is? You have to eat a meal.

As far as I know, fanfan should belong to Dan medicine, and she lost weight through it. For ordinary students, it is no problem to lose weight 15 kg in seven days, but the main thing is to study hard, learn the art of rice, strengthen physical exercise and learn traditional culture. You should know that eating is just a process, and what really changes you is your habit, so you must remember to practice.
