While most parts of the country are enduring a heat wave, Yushu in Qinghai province is drawing a constant flow of visitors, including a group of aerial photographers, from all over the country, with its cool and pleasant weather, beautiful landscape and a variety of mid-summer activities.

With an average altitude of over 4,000 meters, the Yushu Tibetan autonomous prefecture is located in the Sanjiangyuan area, covering the headwaters of the country's three major rivers -- the Yangtze, the Yellow River and the Lancang River.

Blue skies and green mountains are not the only offerings for visitors to Yushu, Vice-Mayor Jiu Wen said at the opening of a national drone photography forum on July 23.
