In 1983, in Nanluo Lane, Beijing, the 28 big bars were pushed and the Shanghai brand four horns were pulled. There is a basket of fresh vegetables and pork belly in the front, and a cardboard box is tied squarely in the back seat. Pedestrians' eyes were glued to the packaging and couldn't be moved away, but I didn't even raise my eyelids. This pile of stuff would not even be as good as a street stall in later generations, but in this era it was worth most of a lifetime's wages. Go home and close the door first, and then figure out how to exchange the ticket.
