Can the old man send carp in the afternoon at the age of 73?

The old man is 73 years old and will send carp in the afternoon. There is a folk saying that seventy-three people are busy, which means that when the old man is seventy-three, he will buy a big carp to make the old man have a happy birthday and good health after eating it, so the old man will send carp in the afternoon when he is seventy-three. This answer is for reference only. Don't be blindly superstitious.
