At the age of 45, the factory's "flowering period" has passed, and Lu Nan's "flowering period" seems to have ended early. The layoff notice was like a dead leaf hitting my head. In order to pay for his son's tuition, he put aside his former "iron rice bowl" honor and set up a food stall in the night market. From being in a hurry to being able to do it with ease, from being ignored to being crowded with diners. He rediscovered the rhythm of his life in the oil, salt, soy sauce and vinegar, and understood: some flowers are not born to compete with other flowers in spring. Their mission is to bloom quietly and stubbornly for themselves in the cold winter when no one cares about them.
