An out-and-out swindler company, they often use the name of buyers in companies such as Dan Guoqiang, Geng, etc. to conduct economic fraud, saying that buyers trust experts, and these experts are all in Beijing, and then collectors are not allowed to go to Beijing, and their company salesmen go, saying that they will buy these expert certificates only after paying the money. I only spent 80,000 yuan and got Ben Geng Chang Bao, Ma Weidou and Li Jianchen. Then I let you do the test and pay 20 thousand yuan. The test result must be wrong, so the buyer doesn't want it. In fact, their company never went to Beijing. Later, I contacted Ma Weidou, who couldn't prove anything at all. The teacher is not at home at all, but he is in Taiwan Province, a fairy, and Geng is in the Forbidden City. Ordinary people don't see it at all. Three people sign it one day, and it's a city-wide scam. Be careful, this Ding Xuan!
