重庆自古以来就是长江上游的商业重镇。“重庆者蜀物所萃,亦四方商贾辐地也。” 秦时,重庆的开发已初具规模。巴寡妇清,以丹砂致富,家财万贯,为秦始皇所礼重,并为她筑“怀清台”(在今长寿县千佛乡)。到了西汉,重庆的手工业和商业进一步得到发展,使重庆成为重要物资集散地。 Chongqing has been a commercial center in the upper reaches of the Yangtze River since ancient times. “Chongqing is a collection of artifacts and also has four merchants.” During Qin’s time, Chongqing’s development has begun to take shape. Widows and widows made themselves rich and wealthy. They were wealthy for the Qinshihuang and built her “Huiqingtai” (in this case, Qianfo Township, Changshou County). In the Western Han Dynasty, Chongqing’s handicrafts and commerce were further developed, making Chongqing an important material distribution center.
