Tchen believes the Council for Cultural Affairs should support the principle of cultural diversity, with equal attention to Taiwanese, aboriginal, Chinese, and Western cultures. Explaining her belief in cultural diversity, She says, "The roots of Taiwanese culture were absorbed over several centuries of assimilation and accumulation from various diverse cultures.
她主張未來文建會將採本土、原住民、中國、歐美等文化並重的多元文化原則，因為「台灣文化的根是幾百年來吸收、內化各種文化累積而成，內容才得以豐富。」
