Hoang Lien Son (Hoàng Liên) / Hoang Lien National Park

Hoang Lien Son (Hoàng Liên) refers to the Hoang Lien range and the protected area known as Hoang Lien National Park in northern Vietnam. Sources identify the park as covering approximately 68,569 hectares of largely montane terrain with elevations mostly between 1,000 and 3,000 meters, and place it administratively in the districts of Sa Pa and Than Uyên in Lào Cai Province and part of Phong Thổ District in Lai Châu Province. The supplied materials do not provide founding dates, detailed administrative history, or precise coordinates for Fansipan within the supplied excerpts. A Wikidata entry also lists 'Hoàng Liên Sơn' as a former province, but the provided sources do not reconcile that administrative label with the current park/range designation. Reported paranormal material specifically tying Hoang Lien Son or the Fansipan area to a named phenomenon called the 'Mist of the Dead' is not present in the provided sources. Literary archives included in the research contain fictional narratives with supernatural motifs, but those texts do not offer verifiable, site-specific folklore, eyewitness accounts, named spirits, or investigative findings linked to Hoang Lien Son. As a result, no concrete paranormal claims or local entities are asserted here beyond noting that such tales were not documented in the supplied source set. Further fieldwork or consultation of local Vietnamese-language folklore collections, ethnographies, regional newspapers, or oral-history sources would be required to document any genuine 'Mist of the Dead' tradition or other supernatural reports associated with Hoang Lien Son / Fansipan.
