Abstract
A total solar eclipse was recorded in a classic Chinese book with the title The Travels of an Alchemist: the Journey of the Taoist Ch’ang Ch’un from China to the Hindukush at the Sumons of Chingiz Khan. In the present paper, possible locations of the solar eclipse observation are investigated, taking into account the geographical characteristics of local environments. With a modern astronomical planetary ephemeris, the authors confirm the observation records and derive an upper limit of +768 seconds for the Δ T value at the epoch A.D. 1221.
