I made it at my mom's friend's house, but it's just a small shop. Because of acquaintances. Yes 1500.

But it seems to be cheaper now. 1200 or so

But I suggest you go to that big hospital.

Jiahong Stomatological Hospital is very good. It's opposite Shenlong Park. But it's expensive.

One of my classmates got more than 1000 at the Municipal Stomatological Hospital. I don't know the details.
