The Great Wall of China - PowerPoint by rt3463df


									The Great Wall of China
- After the emperor unified the country in 214
  BC, he ordered the construction of the wall. It
  took about ten years to finish and the wall
  stretched from Linzhao (in the eastern part of
  today's Gansu Province) in the west to Liaodong
  (in today's Jilin Province) in the east. The wall
  not only served as a defense in the north but
  also symbolized the power of the emperor.
                  History Con’t
- The great wall originated     - It was not until the Qin
  as a military fortification     Dynasty that the separate
  against intrusion by            walls, constructed by the
  tribes on the borders           states of Qin, Yan and
  during the earlier Zhou         Zhou kingdoms, were
  Dynasty                         connected to form a
                                  defensive system on the
                                  northern border of the
   Because many people died while building the
    wall, it has obtained the gruesome title, "longest
    cemetery on Earth" or "the long graveyard".
    Their bodies were not entombed in the wall,
    however. A body buried in the wall would have
    weakened its structure, so workers were buried
    nearby instead.
   bricks and granite were used when the workers laid the
    foundation of the wall and sophisticated designs and
    passes were built in the places of strategic importance.

   While the sections in eastern China were mainly made
    with bricks and chiseled stones, those in western China
    were made with less durable materials (often with clay
    or pounded earth reinforced with tree branches).
   Parts of the Great Wall Include:

       Passes, Beacon Towers, and Walls
   Situated at key positions, usually on trade routes, passes were
    needed to allow controlled entry to and exit from Chinese
   As major strongholds along the wall, passes usually are
    located at key positions such as intersections with trade
                Beacon Towers
   Beacon Towers, also
    known as beacons were
    used for communication
    between army units
   The body of the wall
    usually stood 21.3 feet
    (6.5 meters) wide at the
    base and 19 feet (5.8
    meters) at the top, with
    an average height of 23
    to 26 feet (7 to 8 meters),
    or a bit lower on steep
          Why was the wall built?
   To serve as lookout posts - The ancient Chinese
    had rational fears about being invaded by nomadic
    armies from the north.
   To provide the army with a swift early
    warning system - Fire signals (nighttime) and
    smoke signals (daytime) were relayed from one
    watchtower to another. Messages could be
    rapidly sent over great distances.
   To create an elevated
    military roadway
    through the rugged
    terrain - This helped
    speed the deployment of
    soldiers from one area to
    another along the Great
    Wall of China.
   To impede invaders - This worked against
    feeble armies. However, the wall would serve
    more as a psychological than a physical barrier
    against a determined, well-manned military
    force. A formidable invader could easily breach
    a lightly guarded part of the wall. Or, it could
    muscle its way through one of the gaps between
    the individual wall sections.
     What condition is the wall in?
   While some portions near tourist centers have
    been preserved and even reconstructed, in most
    locations the Wall is in disrepair serving as a
    playground for some villages and a source of
    stones to rebuild houses and roads
       The Great Wall from Space
   Contrary to popular belief, the Great Wall
    cannot be seen from space without the
    proper equipment. It would be like trying to
    see a single piece of thread from the top of a
    50 story building
   However, with the
    proper telescope, the
    Wall can be seen!
          The Best Time to Go?
   The best month to visit the wall is October. The
    weather will be sunny, and there will be less
    chance of rain than on other months

   The worst months to go are between November
    and April because it’s the dry season and the
    weather is bitterly cold.
    Why do you want to visit the Great
   With a history of more than 2000 years, the
    Great Wall is one of the most appealing
    attractions around the world because of its
    architectural grandeur and historical significance.

   It became a world heritage site by UNESCO in
   As one of the Eight Wonders in the world, the
    Great Wall of China has become the symbol of
    the Chinese nation and its culture

   There is a saying in China that states "The man
    who doesn't visit the Wall has never been to
