However，estimates of lead output and sales volumes of this area remain largely obscure for historians，leaving the evaluation of its compact on local society groundless. Based on detailed textual study of the mining factories memoirs of annual sales volumes found in Qing archives，this paper provides a new estimate of the lead output and sales volume in this area and alsoexamines the previous calculatingb methods of mine output volume of the Qing dynasty.
