In the morning, my mother and I went shopping. I saw a farmer's uncle selling vegetables. In front of him stood an aunt. The farmer's uncle shouted: "Come and buy! Big and sweet Chinese cabbage! 2 yuan a catty! " Aunt said, "Uncle, how much is 2 Jin?" The farmer's uncle said, "4 yuan." Aunt said, "Can you make it cheaper?" The farmer's uncle said, "I got up at three in the morning to pick this." I looked at the farmer's uncle carefully. He wears a straw hat on his head, with three deep wrinkles on his forehead, small eyes and wrinkles on his mouth. Wearing a white vest, gray trousers and a belted waist. Aunt said, "Is it cheaper?" The farmer's uncle hesitated and said, "well, count you three pieces." The farmer's uncle picked up a bundle of cabbage and weighed it on the scale. The farmer's uncle weighed it and said, "A little more, it can be counted as three pieces!" " "The farmer's uncle put down his scale, picked up a bag, put the cabbage in the bag and gave it to his aunt, who paid for it. The farmer's uncle said, "Go slowly and come again next time." Then he rubbed his sore waist and sat down slowly.
