The
Great Wall of China is
a
superb work of military engineering and is built across the hills of
Northern
China. It took 300,000 men over 10 years to build the wall. It was
built in mud
and stone. The eastern sections were built in brick. In building the
wall, Shih
Hyang Ti emptied the royal treasury.
In 1324
Genghis Khan led
his
troops over the wall and established the Mongol dynasty. In 1368 the
Ming
Dynasty drove back the Mongols out of China. The Ming rulers
transferred the
Capital from Nanking to Peking. In 1420 emperor Yung Lo, rebuilt the
Great
Wall.
