Make more friends, go out to parties, invite people to eat and drink, and then you will know your friends' friends through friends.

In a year's time, even if you make more than twenty new friends.

Then a dozen are nonsense, the remaining four or five will always match you, and then it is not difficult to choose one of the four or five.

It's simple, but how to play depends on your ability. If it's not difficult, it's time to go on a blind date.
