The
Atlas is considered the most authoritative compendium of ancient place names and administrative boundaries, and a tremendous improvement on its predecessor,
Yang Shoujing's
Lidai yudi tu (
Yangtu, "Yang's atlas", 1906–1911). However, more controversial has been Tan's historical conception: This vision has been criticized as anachronistically projecting 20th-century minority policy and border claims into the distant past, resulting in a distorted view of the history of peripheral areas, portraying their incorporation into China as an inevitable organic process, rather than the result of conquest. Similarly, early states are often given overly precise and extensive outer borders, often based on contentious claims. In his afterword to volume 8, written in 1987, Tan identified the
Atlas's indiscriminate inclusion of
jimi and
tusi areas within imperial territory as a flaw. ==See also==
