Introduction to horse-tying posts and stepping stones: Horse-tying posts and stepping stones are located 10 kilometers southwest of Shengjin Township, Turpan City. Looking from the northwest of National Highway 312, there is a stone pillar on the top of Fengfeng Flame Mountain. It stands majestically, shaped like a wooden stake, and is known as the "horse-tethering stake". It is said that when Tang Monk passed by Xitian while studying for Buddhist scriptures, he tied a white dragon horse to a stone pillar, hence the name of the horse-tying post. Not far from the horse-tying post, there is a huge stone, which is said to be the stepping stone used by Tang Monk when he mounted his horse.
