Abstract: Everything I never told you, the first work of Chinese American writer Celeste Ng, describes a story of an interracial family living in America. This novel reveals difficulties of the Chinese immigrants who try to merge into American society and how they get rid of the interracial pressure through the description of every family member's mind. This paper analyzes the Chinese and American cultural conflicts embodied in Everything I never told you from the perspective of five dimensions of Hofstede's cultural dimensions theory——power distance, individualism vs. collectivism, masculinity vs. femininity, uncertainty avoidance, long-term orientation vs. short-term orientation.
