When talking about "cabbage Zhang" in the streets, everyone gives a thumbs up. I was raised by my grandfather when I was an orphan at the age of six. The land in my yard was transformed into a greenhouse to grow only Chinese cabbage. I was admitted to the Agricultural College because the tuition was low and subsidies were abundant. After graduation, I took over the mottled tricycle and continued to drive. With my eyes closed, I could tell which building the regular customers lived in and which unit they were. My grandfather lay in bed for more than a year and never got up. I pushed the cart through the streets and hung up the "Baicai Zhang" sign. The shout came from the alley in the morning light, and a law enforcement vehicle with blue letters on a white background had parked at the corner of the alley opposite.
