Line 72:
According to Zhouyi Qingbo Miscellaneous Notes, the main industries in China in the Tang Dynasty were "36 lines", namely: butcher shop, palace powder, ready-made clothes, jade, jewelry, silk, paper, seafood, fresh fish, stationery, tea, bamboo and wood, rice wine, ironware, ancient embroidery, needle and thread, soup shop and medicine.
Tsui Hark said in Clearing Money, Agriculture, Industry and Commerce: "Thirty-six walkers, various occupations. As far as the division of labor is concerned, it is 36 lines, 72 lines, and 360 lines ten times. " It can be seen that "72 lines" is a virtual indicator, and the 72 lines or 360 lines that people often say today are not specific numbers. In fact, the division of labor in social industries has far exceeded the 72nd line.
