On August 20th, 2020, I, Yu Yiqun, illegally linked the certificate of second-class builder to Xinchang Chen Tong Construction Co., Ltd. through Hangzhou Bluesmith Construction Engineering Management Co., Ltd., and the Bluesmith was owned by the intermediary, legal person Tao Jingnan and salesman Yang Lu. During this period, the Bluesmith resold the certificate to "Hangzhou Shengcheng Enterprise Management Co., Ltd." without my permission. I sent my ID card and diploma to Chen Tong Company for registration on August 20th, and I didn't receive any fees after that. The blue carpenter has been prevaricating for various reasons and has been dragging his feet and not giving money. Later, Chen Tong found my personal information in the public security department and contacted me to understand the cause of the incident. Finally, I learned that Chen Tong had made money, but the money had been too prosperous to take it out. Bluesmith knows that it is illegal to hang the certificate. For a leather bag company like him, we can do something about him. Nothing matters until it is solved in the end. Prosecuting the Bluesmith will definitely be rejected, because it is illegal to hang the certificate itself. Complaining that Chen Tong is inhuman, after all, people have already made money. Therefore, you can only report the illegal link of your certificate and you can revoke it. You can cancel it, and it's free. But you must know such a thing, lest more talents study hard for the exam, and finally they are cheated with nothing and can do nothing. Breaking the law is not terrible. What is terrible is that some people use illegal acts to commit the next round of crimes, and more people may choose silence. If these so-called intermediary companies are left unchecked, more and more people will suffer. Some people will say that these are deserved, and they are right, they really deserve it!
