Ef really can't. I studied in the flagship store for a year. I am serious. I haven't missed a class, and I insist on it every week. Finally, the promotion is very limited. I regret wasting my time very much. The cost of time is the most precious. I saw these so-called foreign teachers leave the center and said they would go to the next stop to play. See, foreign teachers are not professional teachers, but people just come to play and work by the way. Don't believe those foreign teachers have any certificates. The difficulty of those certificates is equivalent to China people taking a very simple Putonghua test, and anyone can take it.
