《明史·志·卷五十六》
内商的盐不能迅速获得，边商的盐又不低贱出售，前往换盐渐渐懈怠，存积的滞留与常股相同。
内商之盐不能速获，边商之引又不贱售，报中寝怠，存积之滞遂与常股等。
The salt of inland merchants could not be quickly obtained, and the salt of border merchants was not sold cheaply. Going to exchange for salt gradually slackened, and the accumulation of backlog was the same as the regular stock.
