First of all, they are education and training institutions, and the purpose of calling you is to make you pay tuition. And the tuition is very high, and the class hours are not long, usually three months.

Second, you can really be assigned a job by going in for training, but it is not good. It is said that there are high-paying students, because these students themselves have a foundation, but training is just a springboard. But if you don't know anything, I can tell you that the money you pay is basically for nothing (although you can stop studying, you won't get paid during this period of study).

Finally, what they teach you is the most basic. To put it bluntly, you can teach yourself if you spend some time surfing the Internet. If everyone can learn well in a short time, will anyone go to college and take the postgraduate entrance examination?

Finally, to sum up, this kind of training institution is cheating tuition fees.
