Occupying a strate
gic position at the mouth of a fourteen kilometer long precipitous gorge on the upper reaches of the Peacock River in the north of Korla City, the pass was an important point along the route into the Tarim Basin in the ancient times. A checkpoint was set up in the Kin Dynasty and it was called Tiemen Pass (The Iron Gate) because it was situated on a strategic point and difficult to access. The gorge where the pass is located was called Tieguan Gorge (The Iron Pass Gorge) and now is popularly known as Haman Gully. Here the cliffs are steep and high and the terrain makes climbing difficult. On the cliff beside the checkpoint there is an inscription which means “The Strategic Mountain and the Dangerous River”. On nearby Princess Peak there are two graves in which, legend has it, are buried a couple who died for freedom and love, Princess Tzuohla of Yanqi Kingdom and Tayi, the son of the premier of the kingdom.
