What's the difference between blind date and flash marriage?

. . . . Blind date is a series of dating activities aimed at finding lovers or marriage partners. They won't get married right away. It is common for young people who are busy at work but have not yet fallen in love but are of marriageable age. The main activities are eating, watching movies, singing K and so on. . . The activity of making friends is called "friendship", which is not aimed at marriage, but at finding lovers and both parties are young.

Flash marriage means getting married without the knowledge of people, friends, colleagues, relatives and even parents around both parties. Marriage is as fast as lightning, and no one can find it, so it is called flash marriage. . . . It is usually a form of marriage for some low-key celebrities. Because they don't like lively and grand scenes, there are too many irrelevant people at the wedding, so they only invite some relatives and close friends to hold the wedding in an ordinary place. Often when the outside world hears the news, they are already married, which is unbelievable, so it is called "flash marriage". . .

The above two are completely different behaviors.
