=== Problems with conservation ===

The environment and temperature at Jinsha encourage the growth of bacteria, mosses and cracks.<ref name=":6" />{{rp|267}}<ref name=":8" />{{rp|2}} A high concentration of [[illite]] was found in its soil, which makes the site's features and objects prone to cracking.<ref name=":6" />{{rp|268}}<ref name=":8" />{{rp|8}} There are concerns that the excavation grids and unprotected artefacts are vulnerable to sunlight, birds and wet weather.<ref name=":6" />{{rp|264}} Despite the temperature control system, it remains unstable.<ref name=":6" />{{rp|267}} Poor stabilisation aids the development of pathologies. Ceasing daily water sprinkling around the site has been recommended to reduce the humidity and moisture.<ref name=":6" />{{rp|271}}
