Lin Wan lost her job in the city. Returning home, she only found the rooftop vegetable garden that her grandma had tended for forty years cleared out. Her mother-in-law despised her, a master's degree holder, for growing vegetables, and her brother-in-law had traded the rooftop for money. She accepted the heirloom seeds left by her grandma, tilled the soil and sowed seeds all by herself, learned old-fashioned methods of composting, and grew sandy-fleshed tomatoes from eight plots of land. Vegetables sold for six yuan per catty in the market, and seventeen households upstairs and downstairs ordered vegetables. Hexian offered eight hundred thousand to buy the seed source, but she didn't sign. After a heavy rain, half the building's residents helped her protect the vegetable plots, grandma was discharged and came home, and the family surrounded a table of home-grown vegetables.
