The National Cultural Heritage Administration of China released its first list of major national-level Great Wall sections recently.
Four relic sites from Tang Dynasty (618-907) in Xinjiang Uygur Autonomous Region were included into the list.
They are Tuoxike beacon tower, Kiyakkuduk beacon tower, Kizil Gaha beacon tower and Mazartag fortress.
All the towers were integrated military facilities used to transmit war signals in ancient China.
There are now 212 sections of the Great Wall in Xinjiang on the list.
