Yak near Yamdrok lake, Tibet. It is a long-haired bovinae found throughout the Himalayan region of south Central Asia, the Tibetan Plateau and as far north as Mongolia and Russia. The Tibetan economy is dominated by subsistence agriculture. Due to limited arable land, the primary occupation of the Tibetan Plateau is raising livestock, such as sheep, cattle, goats, camels, yaks, dzo, and horses. The Tibetan yak is an integral part of Tibetan life. (Photo by Dennis Jarvis)

The Longsheng Rice Terraces are located in Longsheng County, about 100 km (2 hours drive) from Guilin, Guangxi, China. The most popular are Ping An Rice Terrace and Jinkeng Rice Terrace. The terraced fields are built along the slope winding from the riverside up to the mountain top, the highest part being 880 m in elevation while the lowest part is 380 m[citation needed]. The coiling line that starts from the mountain foot up to the mountain top divides the mountain into layers of water glittering in the sun in spring, layers of green rice shoots in summer, layers of golden rice in fall, and layers of silvery frost in winter. The terraced fields were mostly built during the Ming Dynasty, about 500 years ago.
