Shanxi Province is situated in the middle of the Yellow River valley, lying between latitude 34°34'-40°44' north and longitude 110°15'-114°32' east. Its location west of the Taihang Mountains gives the province its name, Shanxi, meaning "west of the mountain." Shanxi abounds in tourism resources. Famous spots include the Yungang Caves at Datong City in the north, Wutai Mountain, a sacred place of Buddhism in the central part, and the falls at Hukou in the south, the only waterfall on the Yellow River. The province also encompasses the country's largest temple of martial valor – the Guan Yu Shrine at Xiezhou – and one of the four large whispering buildings in China, the Yingying Pagoda of Pujiu Temple in Yongji County. Statistics show that Shanxi now preserves a total of 31,401 unmovable cultural relics of different kinds. They comprise 2,639 ruins of ancient monuments, 1,666 ancient graves, 18,118 old buildings and memorial structures of historic interest, 300 grottoes and temples, 360 sites bearing ancient vertebrate fossils, 6,852 sites with stone inscriptions and 1,466 old revolutionary sites and memorial buildings. There are 12,345 painted sculptures in these old buildings and memorial structures of historic interest and 26,751 square meters of murals in old temples. Therefore, the province has broad prospects for developing tourism based on its rich cultural relics to make it a pillar sector of the economy.
