Lu Chuan married into the Du Family Grain and Oil Mill for three years, modifying equipment by day and accompanying clients for drinks and chasing orders by night. The factory was saved single-handedly by him, yet he was scolded as a "freeloader" every day by his father-in-law Du Mancang, and considered a disgrace by his wife Du Meiling. At their daughter Doudou's first birthday banquet, where the Du family set up twenty tables, Liu Jinfeng held her grandson and showed off from table to table, while Du Mancang publicly humiliated Lu Chuan, saying, "With a dad like that, even the grandson will be pointed at by the spine." Just at this moment, an old tricycle plastered with the red characters "Agricultural Machinery Repair" rushed to the hotel entrance, and Lu Zhenshan and Wang Xiulan rushed into the banquet hall covered in dust, only to be dragged outward by the security guards.
