Like offline social enrollment training, there are many pitfalls and problems in the enrollment training of WeChat friends circle, such as easy refund of fees and false promises. In order to prevent being deceived, applicants need to improve their ability to distinguish between true and false. Many job advertisements are nominally for members, and some even claim that they can study for free. In fact, they sell products to members through training, such as diet pills, health care products, electrical appliances and so on. However, these goods are likely to be produced or imported without approval and belong to counterfeit products. I also saw it from the mobile phone of the Beijing distribution client, and some fraudulent acts, especially the new fraudulent means in Beijing, will be exposed in time.
