How about Xi 'an Xiaobaitu Stomatological Hospital? Can I do invisible correction? The price is lower than the four doctors? What's the effect?

I am a patient there now, and I feel that the service there is generally good (except for a few, that is, that kind of thing ...). I can do invisible correction, and the price should be much cheaper than that of No.4 Medical College. Generally, it is estimated to be around 10,000 now, even if the total cost I calculated for you before is only 7,000 to 8,000, but the subsequent series of tooth cleaning (optional) depends on whether you have cavities, and if you have them, you need to make them up.
