Another of Loung’s brothers, Kim is ten years old at the beginning of the story. His name means “gold” in Chinese, though Ma calls him “little monkey” because he is so agile and small. Loung initially finds his antics annoying, reflecting that it must be an older brother’s duty to irritate his sisters. Kim takes great pride in helping his family under the Khmer Rouge, however. Pa helps him secures work with the village chief of Ro Leap, a position that allows Kim to obtain leftover food that saves his parents and siblings from starvation. Kim also knows more about the political situation in Cambodia than Loung and often explains things to her, such as the concept of capitalism. Before Pa is taken away by soldiers, he tells Kim that he must become the man of the house despite being only twelve years old. Though Kim is terrified, he takes this duty seriously and steals corn from the village field to again fend off starvation for his family. One night he is caught by soldiers, who beat him brutally. He never steals again, and Loung reflects that though Kim must act like the man of the house, he is still only a little boy. When the Vietnamese defeat the Khmer Rouge, Kim finds both Chou and Loung and takes the lead on their journey to the displacement camp in Pursat City. There, he continues to do whatever he can to provide for his sisters, causing Loung to reflect upon how mature he has become over the years. Kim eventually makes it to a Thai refugee camp in 1988, though changing American refugee laws mean Meng is only able to get his brother Kim as far as France.
