The photo taken on June 10, 2006 shows grass-covered Riyue Mountain near Qinghai Lake in northwest China's Qinghai Province. The mountain, where Princess Wen Cheng had a rest on her way from Chang'an, capital of Tang Dynasty (618-907), to Lhasa over 1,300 years ago, is about one hour's drive from Xining, capital of Qinghai Province. Princess Wen Cheng was a daughter of Li Shimin, Emperor of Tang Dynasty, who married Tibetan King Songtsan Gambo in 641. She took with her large quantities of silk fabrics, handicrafts and farm tools to Tibet. Her statue is enshrined on the mountain now. (Xinhua Photo)
