The Sound of Tibetan Gust

In TIBETAN, the vast hinterland of the Qinghai Tibet Plateau, and by the Tibetan Holy Land "Nianjing Lake", there is a herdsman. In summer, they live by water and grass, with yaks as companions. They live a simple but comfortable life. The sudden snowfall blocked the only way into the mountain, and all the vehicles were unable to pass normally. Yak and human winter supplies have not been fully reserved, if not solved, herdsmen will suffer huge economic losses. In the contradiction, how will they solve the dilemma of life?
