During the anti-epidemic period, the quality of all kinds of medical equipments and health care products used by the public should have been strictly checked. In the face of the new coronavirus, which is so contagious, if the quality of the medical products we use is not up to the mark, it will be impossible for the anti-epidemic to get good results. In the epidemic has just begun to outbreak of January and February, the country's masks are very tight, some drugstores only some masks will often be swept away, in this country are very nervous about the moment, some criminals but the use of people's panic, manufacturing and sales of fake masks do not meet the protection standards, to the people caused by the major economic losses at the same time will also put them in danger. These criminals include the chairman of Beijing's famous pharmacy, Kang Baixin Pharmacy. In January 21st to January 26th of this year, the chairman of Kang Baixin Pharmacy, Li Dong, together with two friends, imported a batch of masks from Shandong, the quality of this batch of masks is very poor, far from the national standard of protection, but Li Dong does not care about these, he wanted to take advantage of the masks when the tension to take advantage of an opportunity to make a fortune, and in the end, this batch of masks to obtain the sale of revenue as high as 4 million yuan. After learning about this, the public security authorities arrested Li Dong and two other accomplices in accordance with the law, and the procuratorate also prosecuted in accordance with the law, and now all three have been sentenced. In my opinion, the behavior of Li Dong, the chairman of Kang Baixin Pharmacy, and the other two accomplices is extremely bad behavior. When the whole country is fighting against the epidemic, these people not only did not want to help fight against the epidemic, but also wanted to take advantage of the opportunity to get rich, and put the safety of the people's lives at risk. Masks regardless of which stage in the development of the epidemic is an important protective supplies, those who bought fake masks think they wear masks on the safe, but do not know someone behind the back? set them up? Who should be responsible for those patients who suffer from new crowns because they wear fake masks? Therefore, I hope that the state can treat this kind of bad behavior and punish it without mercy. Good thing the public security department cracked down in time, and Kang Baixin Pharmacy also promised to pay compensation, resulting in the social impact is not as big as imagined.
