Relic Protection Project Kicks Off in Chongqing This photo taken on Feb. 13, 2003 shows partial inscriptions of Huang Tingjian, a great writer and calligrapher in the Northern Song Dynasty (960-1127), at Baiheliang (White Crane Ridge). Baiheliang is a 1,600 meter-long and 15 meter-wide natural rock ridge located in the upper reaches of the Yangtze River. After the completion of the Three Gorges Project in 2009, the White Crane Ridge will be 40 meters deep underwater.
