'Drum Mountain') near the village of Hecun; a southern group (Chinese: 南响堂山; pinyin: Nán Xiǎngtángshān) on Mount Fu; and a site at Shuiyusi that is also known as "Little Xiangtangshan" (Chinese: 小响堂山; pinyin: Xiǎo Xiǎngtángshān).
Construction of the caves in the southern group started at the initiative of a monk, Hui Yi of the Linghua temple, in 565.
The project was continued under the sponsorship of Gao Anahong, the king of Huai Ying and one of the highest official in the Northern Qi dynasty.
A number were sold to the American collector Charles Freer by the art dealer C.T.
Many are now in the Freer Gallery in Washington, D.C.[2] (Chinese regulations and Western museum practices now promote protection of such cultural treasures) [3] The caves are a Major Historical and Cultural Site Protected at the National Level (designation 1-40).
