Abstract: In the past, when people talked about the Chinese professional painter ZHANG Da-qian's patriotism, they started from his subjects of paintings. And in most cases, they involved themselves in the discussion with the content and forms of ZHANG's paintings as the arguments and his dressing as the cut-in point. And then, ZHANG invested a large amount of money in the building of Bade Park and Moye Elegant Cottage and he himself participated in the construction of the two, is there any relation between his action and patriotism? This paper has first compared the meanings of the words “country” and “state”, and probed into the signified and signifier of the nation's concept, i.e. “country”. Secondly, it has taken houses as media and analyzed the significance of ZHANG's construction of three parks with Mcluhan's theories, which came from his belief in and sentimental attachment to the concept of a nation which had formed since his childhood. Accordingly, this paper holds that though since the 1950s ZHANG had lived overseas, he expressed his deep love for his motherland with the construction of the Chinese classic gardens.
