In other words, all parents are concerned about this problem ~ I consulted my children before signing up, but now I don't remember. I only remember that their foreign teachers seemed to have passed two very strict international teacher qualifications and had more than a few years of teaching experience, but what I valued most at that time was the good time for foreign teachers to improve their children, so I signed them up and the reading effect was not bad. At least now I don't have to worry about English. You can ask again.
