Why is "Matchmaker" also called "Iceman"?

For a long time, there are many nicknames about matchmakers, such as Yue Lao, Hong Niang, Zhang Jian and Zhike. Take The Iceman as an example, there is a very interesting story. According to the Book of Jin, Xiaolian Linghu had a dream that she was walking on a frozen lake and talking to people under the ice, and suddenly woke up. Some fortune tellers explained this dream: "Ice is Yang, ice is Yin, and things of Yin and Yang are also;": A scholar returns to his wife, but the ice is uncertain and the marriage is successful. You are on the ice, and you talk to people on the ice. This is a matter of duplicity, and the media is also involved. You should be a matchmaker and marry Bing. "According to today's words, that is to say, you can stand on the ice and talk to people under the ice, symbolizing that you are reconciling Yin and Yang, and reconciling Yin and Yang is to be a medium, and you will be a matchmaker for others. But this media is not easy to do. It takes your enthusiasm to melt the ice and both men and women can get married. Since then, "Iceman" has been used as a matchmaker, which is also called "making ice". This is also reflected in vernacular novels, such as "Ancient and Modern Wonders" Volume 41. " This kind of matchmaking is good for an iceman. Unless his daughter doesn't give up until she gets married, there will be many men and women. In Jin Yong's famous novel "The Dragon Slayer by Eternal Adversity", Yin Susu and Zhang Cuishan, two people who told the truth to the judge, finally became a loving couple by making an iceman with Xie Xun.
