Ningxia
has a fame of "The Museum of Great Wall", from it we can know
the Great wall in Ningxia is very special.
The great wall in Ningxia was initially built in the Warring States Period
(475-221 BC), then continued during the successive dynasties Qin, Han,
Sui, Tang, and ended in the Ming Dynasty. The originally length was 1500
kilometers. The Qin wall is considered as one of the main part, which
was built across the southern part of Ningxia from east to west. The wall
was wandering on the steep mountain ridges and along river gorges to make
good use of these natural barriers. Some sections have remained in good
shape through the ages, giving the evidence to its reputation "the
world's wonder".
