In recent years, chaos has occurred frequently in the field of prepaid consumption, with some businesses closing down and running away due to poor management and inability to sustain themselves, resulting in damage to consumer rights and causing a series of problems such as difficulty in refunding fees and protecting rights. In response to this, the public security organs in Shandong Province have taken measures such as "malicious store closures" and "professional store closures" against a small number of businesses that have infringed on the rights and interests of the masses, as well as economic crimes such as contract fraud, embezzlement of funds, and misappropriation of public prepayments during business operations. Cases involving large amounts of money, strong public feedback, and wide social impact have been subject to provincial and departmental supervision. At the same time, we will deepen collaborative governance, work together with market supervision, education, sports and other departments, carefully study the measures for investigating and rectifying prominent problems in online training institutions, regularly consult and judge difficult problems, improve the mechanism for connecting execution, implement abnormal dynamic monitoring of operating institutions, jointly carry out research and judgment, and resolve risks and hidden dangers in advance. The public security organs in Shandong also actively promote the "Three Checks and Three Retains" prevention law to consumers through media platforms, namely: first, check the qualifications of institutions and select legitimate registered enterprises; Check the business situation and be alert to ultra-low price promotions; Check social evaluations three times and refer to the reputation of third-party platforms. At the same time, consumers are reminded to keep relevant prepaid consumption contract agreements, payment vouchers, communication records, and other key evidence. We call on consumers to choose prepaid education and training institutions rationally, pay attention to changes in the business situation of merchants in a timely manner, and be aware of abnormal actions such as frequent changes in legal persons, arrears of employee wages, and significant adjustments to business service projects. Once they encounter problems of damaged rights and interests, please report to the public security organs, consumer associations, market supervision departments, etc. as soon as possible. The regulatory departments will implement coordinated disposal. For those who constitute crimes, the public security organs will crack down severely in accordance with the law and fully protect the legitimate rights and interests of the masses. (New Society)
