STRUCTURE







                   The structure is not in a single long
                   line! In fact, there is not one wall,
                   but  many  walls,  in  the  plural.  It
                   is  a  defensive  network  consisting
                   of  many  walls  and  forts  built  in
                   different  historical  periods,  with
                   some  segments  scattering  while
                   some  running  parallel.  In  some
                   places,  the  wall  doubles  or  even
                   triples itself.
