Gazelles are seen near the frozen Namsto Lake in southwest China's Tibet Autonomous Region, Jan. 17, 2019. In the past, herdsmen in Tibet endured a ridiculously long, cold winter from October to the end of June, before moving to the summer meadow. They had no fixed residence and migrated when the seasons changed, taking their tents, kitchen utensils and other necessities on horseback. Nowadays, most herdsmen benefit from local resettlement program. They said goodbye to their winter hovels and moved into brick-and-mortar Tibetan-style homes. (Xinhua/Purbu Zhaxi)
