"Master, master, I'm back!" A boy of eleven or twelve years old rushed towards a thatched house halfway up the mountain. The young man was holding the Dukang he had just bought from Shanxia and a bag of fried peanuts.
An old man slowly walked out of the house. The old man's back was slightly hunched, and although there were many wrinkles on his face, it was not ugly. The setting sun shone on his face, making him more kind.
Seeing the young man, the wrinkles at the corners of his eyes were a little more numerous. He smiled and said, "You brat, I'm finally back. Why did it take you so long this time?" The young man scratched his head and said breathlessly, "It's too... Far." After speaking, he stuck out his tongue again.
The old man took the wine and fried peanuts from the young man's hand with his left hand, raised his right hand and hit the young man's forehead, "Ouch", the young man immediately shouted, "Master, what are you doing?" The old man said, "You went down the mountain at noon. At your speed, even if the mountain is ten miles away from here, you have to go back and forth twice, let alone only two miles." After that, he carried the things into the house.
Intention: What is intention?
