You can pay attention to Xiaole. I have friends who study in Anyang Triangle. At first, I thought that most of these schools were unreliable and pure fraud. However, after studying for 4 months, I actually opened my own shop as a boss. This really shocked me, but I still have to keep my eyes open. There are many such schools now, most of which are exaggerated. I can't draw a conclusion until I have really experienced them.
I hope my answer can help you!
