An untapped virgin forest, a natural oxygen bar, this is the South Yigou. When I first heard the name, I always linked it to Nanniwan. In Linzhi, I saw such a poster: a green wooden dam, a log cabin, a row of trees of various shapes. Did not remember the name of the poster, but fixed the beautiful picture in my mind. When this picture appeared in front of me, I also recorded the beautiful name of Nanyigou. "Southern", Tibetan means "land where the gods live." Look at the flowing water, the wildflowers of the stars, the grass dams of the yak, the long flowing plants........ I think, even if it is not the place where the gods live, it must be a place where the gods are especially cared for. . I greedily breathe the fresh air, imagining that I can collect the oxygen from the south gully and store it in the body as a small oxygen bar, so I don't have to worry about the altitude sickness of the journey back!
