It is generally believed that in ancient times, men and women had never met before marriage, and their marriage was "blind marriage and dumb marriage", but in fact, this custom had changed in the Tang and Song dynasties. At that time, there were also some "blind dates", such as March 3, the Lantern Festival, and so on. Men and women still had the opportunity to "see" each other. In the new era, after the freedom of love, people's blind date mainly refers to the introduction of relatives and neighbors and the newspaper. At the beginning of the 21st century, traditional marriage websites have sprung up. However, in recent years, because of its chaos (such as fabricating virtual objects, inducing consumption, "pig killing plate" fraud, etc.), and the birth of various social software, traditional marriage websites have been greatly impacted. In addition, in this process, all kinds of park matchmaking corners, matchmaking programs and matchmaking cultural festivals are also "not idle". The matchmaking corners have "gone abroad", and the middle-aged and old people's matchmaking programs are frequently "out of the circle"... Although there are various matchmaking modes, it seems that "chatting" and "suitable conditions" are not easy to get.
