Sister's housekeeping is very deceptive. Are there any exposed scams?

The most profitable should be their enrollment teachers, who will charge you money in various names, start training from 2980 yuan, and then one training course will be over and you will be allowed to study other courses. Otherwise, you will be threatened, you won't be introduced to a job, and you will be asked to find a job yourself, such as babysitting, cleaning, and hourly work, which is completely different from the professional jobs they have trained. I hope everyone will keep their eyes open. I was cheated. I just hope that everyone will not be cheated by the silly big sister's domestic swindler.
