The application of brainwashing is actually very extensive. From birth, parents began to brainwash their children, but at this time, the individual did not have any cognition, so it was not brainwashing, but it was attributed to brainwashing. So the first time human beings were brainwashed, they must have started to speak. Moreover, influenced by his parents, the consciousness and knowledge he received in the process of growing up will have an important impact on his life. This is why more parents know that their cognition is limited and hope that their children will be better than themselves in the future, so they let their children participate in various special classes from an early age and accept knowledge other than their parents. This is the earliest brainwashing of human beings, but the brainwashing of parents is fearless and selfless, which is different from the brainwashing methods that appeared in society later. Various standards and intensive indoctrination of society and institutions are also a kind of brainwashing, including various advertisements and information seen on the road and online. It is a brainwashing process, so a special management department is set up to prevent the harm of brainwashing information to positive social information and mainstream values. However, if political brainwashing is put into the ruling management, it may be that this person's ability, knowledge and even knowledge hinder the instillation of a certain sense of political management, so he has the opportunity to face being brainwashed secretly. There are several kinds here: the first is the common educational brainwashing in foreign society, which allows people with lower education level than the average social or national education level to receive school education, improve cognitive ability and knowledge through knowledge brainwashing, and reduce the contradiction with others due to unequal knowledge and educational background. This is similar in China, such as nine-year compulsory education, which is a kind of brainwashing of knowledge. The second category is about the brainwashing of the national consciousness of hostile areas and hostile elements. For example, after the 9 1 1 incident, the United States listed some distinctive ethnic groups in the Middle East as high security targets, and made a large number of soft notices to its citizens, such as news, newspapers, interpersonal exchanges, etc., which made most people in China in a relatively high state of alert and even internal conflicts. This is also a more advanced way of brainwashing. In the same example, in order to rule more smoothly, Germany once incited people to hate Jews together, resulting in a large number of massacres of Jews by government forces, which made Jews in an extremely deteriorating situation. Aside from the consideration of political needs, if a German and a group of Jews were brainwashed by politics, they would do the same thing, which is also a typical way of brainwashing under the rule. For another example, in China, if some organizations try to cover up some unknown negative events, the leadership may mobilize its lower-level employees to jointly block and deny the events, and will make key remarks and public opinion attacks on the leaker, emphasizing that all problems are his problems, and most employees are instilled with relevant "negative information" without knowing it at all, and innocent people will become the targets of attacks. When "negative information" is constantly spread, it is also a way of brainwashing in order to achieve the goal of exposing negative events faster than the other party. Moreover, this brainwashing method is very common in office political struggles and will also appear in regional management. It is a common means of political brainwashing, also known as political struggle and ideological struggle.
