Built in 1715, the mound was initiated by the 1st Living Buddha Jiana Zongqiupawen of Jiegu Monastery, hence it is also known as Jiana Mani Stone Mound. In Tibetan, it is called Duobong, which translates to "one hundred thousand scripture stones". Xinzhai Monastery stands to its south, while walls made of mani stones enclose it on other sides, with prayer flags hanging atop the stone ramparts.
It is said that the inscriptions on these mani stones contain nearly 20 billion characters, earning it the title of the World’s Largest Stone Carving Library. Every year from the 14th to the 16th day of the twelfth lunar month, Tibetan people from Xizang, Sichuan and Qinghai gather here. They walk circumambulations around the mound, present new mani stones and dance joyfully afterwards.
On the eastern side stand eight white pagodas and a huge prayer wheel. The rest of the mound is covered with mani stones carved with Buddha statues and scriptures, featuring exquisite craftsmanship and harmonious color matching. Many local artisans inherit the age-old carving skills. They carve devoutly to accumulate merits and pray for all living beings, with the clink of chisels blending with the chanting of the six-syllable mantra.
Visitors often purchase mani stones, make wishes and place them on the stone walls. Every day, numerous Tibetans spin hand prayer wheels while walking around the mound; each turn is equivalent to reciting the scriptures inscribed inside.
