1. The certainty of mixed online media. As a kind of media, the network itself has won people's love for its advantages of rapidly spreading a large amount of information. However, it is precisely because of this situation that people can't make friends online, and people have to be wary of their judgmental identity and ignorance of their personality. How many cases of netizens meeting and finally causing tragedy are not enough to sound the alarm? As the saying goes, "it is difficult to know each other's faces", what's more, a rope can know each other? Even if she is the red line cast by the matchmaker, it can't erase the essence of her red line. All the cases of netizens have proved that she is a blood line, a red line and a line stained with blood. 2. The fuzziness of virtual world and real emotion. With the help of the internet, we have met friends from all corners of the country, but there are several who can really be called friends. His virtual world tends to paralyze our minds. It often makes us in a beautiful fantasy state, and it is difficult to face everything around us in real life. Blind emotions not only can't help us make friends, but let us know people we shouldn't know in society, causing unnecessary trouble. It is difficult to judge the accurate attribute of virtual and real in life emotionally, and there is great ambiguity. Since it is vague, why should we make our emotions vague? It is a fact that online dating is fast, and it is also a reality that the consequences of online dating are not good. Since the facts in reality reflect that the consequences of online dating are very bad, both facts and reality show that virtual is not real after all, and existence and pay are not equal. When will such a vague account be settled? 3. The contrast between venting feelings and playing with feelings. When people make friends online, many people think that they have troubles and can talk to each other unscrupulously, thus reducing the pressure. The other party seems to care very much, but in fact they are talking with a playful attitude. Your sincerity is rewarded with disdain. On the surface, you are comforted, but in fact, like a hedgehog, you tell the most fatal weakness to people of unknown origin. This will only increase your danger. Sometimes even both sides talk with a playful attitude, knowing that friends in the network can't be trusted, but they still want to play. This situation itself reflects that friends in the network are just illusions, which fully proves that online dating does more harm than good, because it makes people lie more. Even better at playing with each other. 4. The intrusion of bad information on health education. There are friends in the network. In reality, good friends rely on the Internet for various reasons. This can only show that, first of all, good friends in life can make good use of the network as a medium. Most people who surf the Internet are mainly boys and girls, and the topic of discussion is ultimately love or something else. On the internet, we can often see the depreciation of love, and the purest thing in life is worthless on the internet. Say a lot of words that trample on innocence at will. There are still many people who use the tone of making friends to spread all kinds of illegal things. This is a real pyramid scheme, and it is easy for people to be deceived or become his followers in some way. Of course, the disadvantages of online dating are far more than the above four points, but as long as we see the great harm of these four points, we have enough reasons to prove our point again. Making friends online does more harm than good!
