Then myna will come and talk to you about what is called "master of ceremonies". The so-called points are control. For example, if a "driver" drives a car, people who drive the car as a "machine" call it a "driver" program. Of course, it also includes many activities. Since it means "ceremony", the person who presides over the ceremony is called "master of ceremonies". But the MC is not so one-sided, it covers a wide range. Everyone is familiar with it. The earliest emcee in my mind should be the one mentioned at the wedding.
This is myna's understanding. If that person has a more accurate and reasonable statement, I hope to exchange it! ! ! ! ! ! !
