市井这个词,是市场的意思。在古代,没有商店和农贸中心,商贩们多聚在井边,人们来担水,顺便购物。“若朝聚井汲水,便将货物於井边货卖,故言市井也。”后来有规模了,形成了商业,城里有市,农村也约定俗成有了赶集的集市。另外一种说法是源自井田,依古制,一井为二十亩田,人们在田里干活,贩夫们在田畔守株待兔。第一种解释妥当些,后一种大概是死脑筋又肯用功的读书人瞎猜出来的。本事,指正经事,是本业,对应着末业。中国古代 The word market is the meaning of the market. In ancient times, there were no shops and farmer's centers. Traders gathered at the well, people came to take care of the water, shopping by the way. “If we draw water toward polyculture, we will sell the goods on the side of the well, so the market is well.” Later, there was a scale, forming a business, a city in the city, and a market in the rural areas, where there was a convention.

Ability to correct the incident, is the industry, corresponding to the end industry. Ancient China
