Space is a relational concept. The Chinese language encodes nine spatial relations, they are: coincidence, interiority, exteriority, superiority, inferiority, anteriority, posteriority, laterality and opposition. It is suggested in the literature that the constant relational nature of space can be expressed by the abstract formal relation between two participants: ‘X spatially relates to Y’, where X is the located object and Y the reference object. The spatial relations mentioned above describe how the located object is related to the reference object. In Chinese spatial relations are encoded by position words, and a reference object is expressed by a compound position word, which, in our definition, refers to the combination of a general NP and a position word, like ‘xiāngzi shàngbiān’ (the top of the box), ‘wūzi lǐbiān’ (the interior of the room), etc.
