Industry in Tsinan is becoming highly developed. Indeed the day we set out to go west, factories on the outskirts were interspersed with fields of wheat, and everywhere on, into and through the Tzupo municipality, wheat fields were interspersed by factories. Tzupo with its five divisions which roughly correspond to five counties, has 2,000,000 people now, 550,000 of them mostly factory workers in the town portions, and the rest commune farmers who cultivate 93,330 hectares of land, all but 26,667 hectares of hills and downs irrigated.
