20220608 In the afternoon: 1. On the way to and from the Yarlung Zangbo Grand Canyon, you can see the Buddha's palm sand dunes on the other side of the river. I thought it was a sand digging site, but the tour guide said that this was natural formation: because this is a wind outlet, the sand of the river beach will blow up, after a cumulative number of millions of years, Gradually become the current "stone quarry", because of the appearance of the Buddha palms, the Tibetans think this is the Buddha's spiritual place, will come to worship every year. 2. This natural landscape has just been developed in recent years, no bus, self-driving can be reached, free. Today is tight, and I have the opportunity to go to the opposite road in the future and watch it from a close angle.
