According to the official account of the unforgettable Amin, the account publishes decrypted videos, and its label is to give you an unknown answer every day. Maybe here, there is a "story" you want to know. Marketing number refers to this kind of self-media writing and publishing with traffic or benefits as the main purpose (free and sharing are not the main purposes). As the producer and disseminator of network information, network marketing number is an important force in the field of network public opinion. Some deliberately dress themselves up as institutional media, but they do not have the qualifications and responsibilities that news media should have. Instead, taking profit as the main purpose and traffic distribution as the main means, it has become the source or promoter of network slander and rumors, damaging the healthy network public opinion ecology. Unforgettable A accounts are all sharing and popular science, so they are not marketing numbers.
