Xin'an Xianzhi (Chinese: 新安縣志; literally Gazetteers of Xin'an County), also known as San On County Gazetteer[1][2] or San On Gazetteer[3][4] in English, were the chorography of the historical Xin'an County (San-On or Sun-On County; literally New Peace County; known at times as the Po-On County (spelt Bao'an in pinyin)) of Guangdong (then Kwangtung) in southern China.
Due to frequent geopolitical changes, the county ceased to exist and became the history and territories of Hong Kong and Shenzhen, metropolises in South China.
Versions of the gazetteer are very important records to study in the area.
