You already said the price. In fact, it is cheaper to go to that hospital, because they are all regular hospitals, and the orthodontic effect is the same. That's good. If you give it to me, I will go back to my hometown (a town), which is also a regular hospital. The price is almost half of what you said and the effect is the same. My hometown also said it was better, and I wouldn't be cheated outside or anything. In fact, the effect of this amendment is the same, mainly depending on the price.
