The three contemporary Chinese architects, namely Yung Ho Chang, Liu Jiakun, and Wang Shu, have often been labeled as the ＇avant-garde＇ or xianfeng architects in China. In response to the xionfeng architect labet, Wang claims that he is a houfeng （rear-guard） architect because of his obsession with traditions. This paper aims to discuss the appropriateness of labeling these architects as ＇avant-garde,＇ xianfeng, or houfeng. Through the theoreticat anatysis of western discourse, notable attributes of the western architectural avant-garde are identified, and a tentative framework is developed to test its validity and usefulness in a non-western context. The term youleng is arguably a better phrase to describe these three Chinese architects considering the heterogeneous trajectory of modernity in China.
