The solutions to cheating in training institutions are as follows: 1. First, we can negotiate with the operators of training institutions and try our best to deal with them. 2. If negotiation fails, the injured party may request the local consumers' association for mediation, or complain to the relevant local administrative department or education department. 3. If the situation is serious and the amount of fraud is large, you can also report the case to the public security organ or bring a lawsuit directly to the court. No matter how much money you are cheated, you should first keep the evidence of fraud and protect your legitimate rights and interests, such as communication records, chat records, transfer or remittance records. Article 266 of the Criminal Law of People's Republic of China (PRC) stipulates that whoever defrauds public or private property in a relatively large amount shall be sentenced to fixed-term imprisonment of not more than three years, criminal detention or public surveillance, and shall also or only be fined; If the amount is huge or there are other serious circumstances, he shall be sentenced to fixed-term imprisonment of not less than three years but not more than ten years and shall also be fined; If the amount is especially huge or there are other especially serious circumstances, he shall be sentenced to fixed-term imprisonment of not less than 10 years or life imprisonment, and shall also be fined or confiscated. Where there are other provisions in this Law, such provisions shall prevail.
