The training of civil servants is similar. The biggest brand is Zhonggong. I have experienced it personally, and the effect is still ok. Generally, such training institutions charge fees in this way. The initial charge is high, about 1W-2W, but you will be refunded about 80%. In fact, the loss is not big, just a few months in the middle, which is equivalent to the time spent by training institutions. And if you pass, you won't get a penny back, but if you pass, you don't care about that little money.
