The five stories in Hunger (1998) deal mainly with the position of Chinese in America, though the last of them is set in pre-Communist Shanghai. Inheritance (2004) is the story of a wealthy but declining family in Republican China, beginning in 1925 and extending through the period of the Japanese invasion and the post-war flight to Taiwan and then the USA.
