Westward from the Yangguan Pass(阳关道：Yánɡɡuān dào )
The Yangguan Pass lies in Nanhu township 70 kilometers southwest of Dunhuang. Yangguan is often mentioned in the mural stories and documents of the Dunhuang Grottoes.

There is an old beacon tower of earth and read, fairly broken, stood at a height of 4.7 meters in the distance like an old man pondering about history. What is interesting is that travellers may often find ancient relics such as bricks, pottery pieces, coins, arrows, bronze decorations, seals and living utensils ranging from the Han to the Song dynasty in the sand dunes in the north and east of the remains of Shouchang city. Round and thin white and black stone pieces may also be found. According to a book found in the Dunhuang cave, the locality, Shazhou, offered to the Tang court twenty sets of chess every year.
