I don't know which famous Portuguese language institutions are there, but don't go to Guangzhou Master Language Training Center. It's terrible. That teacher Kang is the most irresponsible teacher I have ever seen! ! ! ! ! After paying thousands of dollars, what I have learned is not even worth 500! ! ! ! And that teacher Kang is not qualified to be a teacher at all. He may have spent several years in Brazil or Angola, but he is definitely not qualified to be a teacher. There are many mistakes in his teaching! ! ! I asked a very good Brazilian friend of mine, and the Brazilian friend said there was no such expression at all! ! ! My Brazilian friend also told me to change teachers quickly, otherwise I would be harming myself! ! ! !
