Matchmaker plays an important role in the whole blind date process, but not every matchmaker can do it well. There is a saying before blind date that "you can be friends if you can't be lovers", which is a kind of retirement. It seems that most blind dates are very formal and have become a purposeful understanding. The so-called first impression, just look at each other's external image. If it's not your favorite type, it's hard to meet again. This kind of blind date is nothing more than putting two strangers together for an exhibition. It's always awkward to put two strangers together for the purpose of getting married.
