If you look carefully at the recent published Great Wall photographic works, you will quickly find that most of the pictures are taken from Jiankou Great Wall. Due to its unique style, steep mountains and beautiful scenery, Jiankou has become a photographic hotspot and also a hot travel destination these days. 'Jiankou', is translated as 'Arrow Nock' in English, because the shape of the mountain is like an arrow, with the collapsed ridge opening as its arrow nock.
Located in the mountain ridge of Xizhazi Village, about 30km (19 miles) to Huairou County in Beijing, Arrow Nock was an important section of the wall in Ming Dynasty (1368 - 1644). Owing to the need for renovation, it is regarded as one of the most dangerous sections of the Ming's wall. It connects to Mutianyu in the east and joinsHuanghuacheng in the west. From east to north, the wall zigzags 9.3 miles from 'The Ox Horn Edge Wall' to 'The Nine-Eye Tower' via 'The Beijing Knot'. Compared with Mutianyu, the mountain is higher and steeper, while compared with Simatai, it is more winding and varied. It was built from the local material - dolomite. The large pieces of white rock make it striking to the eye at a distance.
There are many famous sections of Arrow Nock, such as 'The Nine-Eye Tower', an important command post during the ancient wars. It has three layers, and there are nine holes which look like nine eyes on each side. 'The Beijing Knot' is the meeting point for three walls coming from different directions. 'The Sky Stair', is a precipitous stair whose angle of elevation is 70 to 80 degrees. It leads to 'The Eagle Flies Facing Upward', a watch tower built on the lofty peaks. It is so dangerous that even eagles have to fly facing upward to reach the top. 'Zhengbei Tower' is the right place to appreciate the beauty of the sunrise and the sunset.
