Is it illegal to sell veterinary drugs and send text messages to customers?

Recently, the Ministry of Industry and Information Technology issued the "Regulations on the Management of Communication Short Messages and Voice Calling Services (Draft for Comment)", which mentioned that "no organization or individual may send commercial short messages or make commercial calls to users without their consent".

In fact, this is not the first time that the Ministry of Industry and Information Technology has issued regulations on spam messages and harassing calls. As early as 20 15, the Ministry of Industry and Information Technology issued the Regulations on the Management of Communication Short Message Service, requiring short message service providers such as China Telecom, China Mobile and China Unicom and voice call service providers to regulate relevant behaviors.
