Zhengzhou Youth Orthodontics Center has good technology and good service attitude. It specializes in orthodontics and does not do anything else. The price is relatively low in Zhengzhou, with a maximum of only 3,000 yuan. College students can also pay in installments. Both of our dormitories worked there. The eldest has only had it for 7 months and is quite satisfied. Pretty fast. It needs to be removed and the retainer put on. Zheng University student.
