According to relevant information, Pinduoduo can report to the police if there is no training source to deceive people. Because the training of goods without goods is a crime of fraud, according to Article 266 of the Criminal Law of People's Republic of China (PRC): "Whoever defrauds public or private property in a large amount shall be sentenced to fixed-term imprisonment of not more than three years, criminal detention or control, 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. Therefore, if there is no training source, you can call the police.
