Abstract：What is the nature of digital twins of city? This article demonstrates the digital twins of a cube exhibited in Bi-City Bien-
nale of Urbanism\Architecture of Hong Kong and Shenzhen (UABB) and elaborates the infnite connections among sce-
narios embedded in limited space. The diverse interactions between visitors and scenarios constitute a typical pattern of
the synaesthetic city, in which subject and object, those perceive and those being perceived, and the virtual and the real,
are integrated into the whole.
