Two tourist guides walk in the Clay Forest in Yuanmou, Chuxiong Yi Autonomous Prefecture, Yunnan Province on September 7, 2008. The tourist attraction reopened on the same day after four days of cleaning-up. It was closed shortly after a 6.1-magnitude earthquake that struck southwestern China on August 30, causing more than 30 of the earth pillars in the Clay Forest to collapse. [Xinhua]
