As the main characteristic of high-ranking burials,tombs with corridors underwent substantial changes in the form and function from the Western Han to the Eastern Han period.During the Western Han period,storage space in tombs with wooden burial chambers was limited,and corridors primarily served the function of"outer coffin-like storage chambers,"while also possessing a distinct hierarchical significance.Large cliff tombs usually have side chambers that also serve as"outer coffin-like storage chambers,"but for these tombs corridors are exclusively symbols of tomb hierarchy.During the transitional period from the Western Han to the Eastern Han and through the Eastern Han period,for tombs with inadequate storage space within the burial chamber,corridors continued to serve the purpose of"outer coffin-like storage chambers."In contrast,large tombs often have side chambers as storage spaces,and thus the corridor gradually evolved into a symbolic representation of patrol paths as seen in aboveground estate architecture.
