原文大夫曰:古之立国家者,开本末之途,通有无之用,市朝从一其求,致士民,聚万货,农商工师,各得所欲,交易而退。《易》曰:“通其变,使民不倦。”故工不出,则农用乏;商不出,则宝货绝。农用乏,则谷不殖,宝货绝,则财用匮。故盐铁、均输,所以通委财而调缓急。罢之,不便也。 The original doctor said: The ancient country, who opened the way to the end, through the use of non-use, City and North Korea from its demand, resulting in civilians, tens of millions of goods, agricultural and commercial engineers, each have their own wishes, trade and retreat. “Easy,” said: “By the change, the people tirelessly.” If the old workers do not work, then the lack of agricultural use; business is not, then the treasure goods must. If agriculture is lacking, the valley will not be cultivated, and the treasures will not be used. Therefore, the salt and iron are lost. Stop it, inconvenience too.
