Of course, when online dating comes to us, we should also correctly recognize its essence and harm. Why do so many people engage in online dating? Its essence lies in the illusion of the network, which is also its charm. Psychologically speaking, we will idealize the object of online dating too much, which will also cause our understanding of each other to be objective and comprehensive, which will be harmful. As a very concealed way of communication, the difference between people's communication with the opposite sex, from the earliest matchmaker introduction, to the later correspondence and telephone contact, to today's online dating, is that you can see, hear and get in touch with the people and things of the other side more or less in other ways, but you can't have an objective understanding of the other side on the Internet, so many people with moral decay will dabble on the Internet and many friends will be affected. Here, we must be aware of such problems, that is, the concealment, deception, degeneration, hypocrisy and so on of the network. Therefore, I suggest that the Internet is only a channel for making friends, and a deeper understanding should be carried out in real life.
