Chongqing Xiaoyu language school
If you live near a university, you can choose to study in an educational institution in Hu Ya. They have schools in all universities in Chongqing, and their headquarters seems to be in Shapingba. The effect is quite good. Many Korean teachers are invited from universities. If you are lucky, you can meet foreign teachers and have a good reputation. I can't remember the telephone number. You can check it online.
