Chang Fu Nan is Chang the coffin maker’s fourth son. The Chang family originally arranges for Fu Nan to marry LuLing. However, they rescind the offer after Precious Auntie’s suicide, fearing that her ghost will haunt their family if LuLing marries into it. After the Lius send LuLing to live in an orphanage, the Changs arrange for Fu Nan to marry LuLing’s sister, GaoLing. Fu Nan is an incompetent opiate addict, and GaoLing is so miserable being married to him that she eventually runs away to live with LuLing at the orphanage. After the war, GaoLing puts further distance between Fu Nan and herself by emigrating to the United States. LuLing remains in Hong Kong and encounters Fu Nan several times as she waits for GaoLing to send for her. During these encounters, Fu Nan threatens to publicly announce the fact that GaoLing and LuLing aren’t really sisters, which would jeopardize GaoLing’s ability to sponsor LuLing’s visa. He also threatens to alert American officials to the fact that he and GaoLing are still legally married, which would compromise her ability to become an American citizen by marrying Edmund Young. However, Fu Nan’s incompetence and debilitating drug addiction ensure that he never actually acts on these threats.
