Nor was entrepreneurship absent. Here is an account of how the price of fuel in Ching-yang county in Shensi was reduced: County magistrate Lu Chen-fei submitted this memorial in 1629: I would observe that south of Ching-yang lies the Ching River, providing direct access to the Wei, on which there is a continuous flow of merchant shipping. Ching-yang, however, relies on the damming of waterways and loads are not carried by boat, the people being unaware of the advantages conferred on them by nature. Leaving aside the question of whether grain might be transported or timber floated in the form of rafts, this is even true of coal. Ching-yang is densely populated and has nothing to burn as firewood.
