To gather information on agricultural mechanization in general and on the question of displacement of labor in densely populated areas in particular, Hsing Nan and others conducted a five-month investigation during late 1963 and early 1964. The tour included visits to regions of extensive cultivation in Heilungkiang, Liaoning (Fushin County), Inner Mongolia, and Peking. The investigation also examined mechanization of irrigation and processing in Hupeh (Hsinchou County and O-ch'eng County, both in the densely populated lakes region east and northeast of Wuhan), Hunan (Hoyang County), Kwangtung (Nanhai and Tungkuan counties, both fairly near Canton in the Pearl River Delta), and Kwangsi. Roughly half of Hsiang Nan's report was devoted to proving that mechanization was a proper policy in these densely populated areas.
