This novel tells the inspirational story of three migrant families living beyond Beijing's Fifth Ring Road. The Barefoot Brothers: Chen Qiusheng and his brother Chen Qiu run a small business in Beijing with their families in tow. They stick together to build their business, but friction never stops. They strive to get ahead, loving and fighting each other in equal measure. Their children, the second generation of rural migrants, also ride the waves of changing times as their fates seesaw between city and countryside, hometown and elsewhere. Sister's Burden: This is the love story of Yao Siyu, a working girl who would rather laugh on a bicycle than cry in a BMW. Bearing the burden of changing her birth family's fortunes, she must choose between her biased mother, her freeloading younger brother, a wealthy Beijing-born second-generation heir who loves her, and the working-class boyfriend she loves. What will she choose? She struggles hard, becomes the person she wants to be, succeeds in Beijing, finds love, and helps her family. Love You Most: This tells the story of Qiu Yehong, who moves to Beijing in her later years to help raise her grandson. After her son makes money in Beijing, he divorces his wife back home, leaving Qiu to care for the boy. Wanting to keep her grandson emotionally and physically healthy and ensure he spends time with his father, she moves to Beijing, raising the boy while helping her son build his business. Life in her son's second marriage turns into a world of extremes.
