Every insurance company has the training your classmates have participated in, and one of them is the insurance agent examination fee, which is the "employment certificate" required by the CIRC. In other words, with the insurance agent certificate, you can choose to be an insurance agent in any company.
As for the cost of this exam and training, there will be differences between companies, and even some companies will provide some incentives, but this is normal and reasonable.
What I want to remind you now is whether your classmate knows that he has participated in the training of business personnel. Don't waste a lot of money and finally feel cheated.
Insurance company is a sunrise industry with great development potential, but for college students who have no experience and interpersonal relationship, it takes effort to do business. If you do well, you will have a better income than white-collar workers, but if you don't do well, you will be very depressed, that's all.
