The Buddha's Palm Sand Dune is located on the north bank of the Brahmaputra River, near the Brahmaputra Grand Canyon. It is named after its shape like the palm of the Buddha with folded hands. Legend has it that there was originally a village under the Buddha Palm Sand Dune called Lagang Village. There was a hunting expert named Deduo in the village. Once when he went hunting, he found a monster chasing a woman, so he rescued the woman. The woman turned out to be a dragon girl. In gratitude for saving his life, he gave Deduo a magic mirror that could predict the future - but he must keep it a secret, otherwise he will change his life. Into a turtle stone. One day, the Dragon King suddenly wanted to bury Lagang Village with sand dunes. Deduo saw this scene in the mirror and told the villagers that after the villagers left the village, in the middle of the night, the village was indeed buried by wind and sand, and Deduo also turned away. For stone. After the villagers of Lagang Village resettled near the sand dunes, they named the new place Samba Village, which means "Secret Village" to commemorate Dedo telling the secret - and the villagers who lost Dedo would never see it again. Don't mention what happened that night.
