François Jullien is a famous French contemporary sinologist. He has been president of the Collège International de Philosophie (1995-1998) and director of the Institut de la Pensée Contemporaine (2002-2011). Currently, he is the Chair of Alterity at the Fondation Maison des Sciences de l'Homme. He has over 30 French publications in the fields of sinology and philosophy, some of which are translated into 25 languages and 16 already have their Chinese versions. From 1978 to 1981 he visited Hong Kong and studied sinology in New Asia Institute of Advanced Chinese Studies under guidance of New Confucian philosophers such as Mou Zong- San and Xu Fu-Guan. Despite his identity as a western researcher of ancient Greek philosophy, he chose to stay in every aspect of Chinese classics and put great effort into them. On the road of poetics, the author persists in having Chinese classics collide with contemporary international literature thus deeply sympathizes the theory of l'écart 'interspace' Jullien proposed in 2011: ＂Make a detour to a remote and adventurous place so as to once again recognize the fertility within the intimate regions upon returning.＂ Leung Ping-Kwan's perspective on poetry and his language features have made him the poet with the most characteristics of Hong Kong. The author has highlighted in her works many times that the vivid depiction and the accurate grasp of the mind within a fixed time and space in the language of Leung Ping-Kwan's poems are rare in the development of modern poetry. This art of Leung leads to the following discussions: How should we perceive this kind of variation in the culture of Chinese poetry? What kind of foreign factor has influenced this culture? Is it as unusual as the way the city Hong Kong is? This article introduces to the reader how Jullien detoured throughout China and reorganized the academic directions of Europe, especially with his concept of l'écart, and hopes to make a clearer observation about this cultural and poetic phenomenon
