Traditional Chinese architecture can be regarded as the building of culture, i.e. image of the architecture can be considered as a certain externalized means of traditional culture. And space as a hero of architecture refl ects characteristics of culture using its form and content. This research explored the common architectural element—gallery from cultural perspective, and proposed gallery as a kind of fuzzy intermediary space, then analyzed its intermediary nature from the perspective of fuzziness, transition, boundary, and placeness, and also its spatial order from the perspective of directivity, dynamics, diachronism and orderliness. On this basis, spatial characteristics of gallery beneath the surface were explored.
