Three brothers, the eldest is called age, the second is called culture, and the third is called joke. Parents are old, and their legs and feet are inconvenient. Three brothers go up the mountain to cut firewood. There are three brothers, the eldest is called the third, the second is called culture, and the third is called a joke. Their parents are too old to move easily, so the three brothers picked up the hill. Walking back, their neighbors saw the fathers of the three brothers and asked, "What's up?" Father: "I have no culture when I am older. I am a little joking."
