Method

The mechanism of the 'civilian tuntian' system as implemented by Cao Cao had its basis in government organisation, encouragement and, to some extent, coercion. Peasants without land, refugees and soldiers were assigned to plots of land which they were to farm, while the implements required (such as ploughs and oxen) were provided by the government at a low price. In exchange for this, the peasant was to give over half of his harvest to the government.

The tuntian system had its origins in the military, and for much of the Han dynasty the land in question was farmed by soldiers on orders of the military authorities; in this case all of the crop harvested was to be kept by the military for supply uses, following the example set by Emperor Wu. Cao Cao's innovation was the introduction of the 'civilian tuntian' on a large scale both for common people and for soldiers during peacetime, whereby he successfully solved two great economic problems facing his administration: the large number of unemployed refugees, and the great tracts of land abandoned by big proprietors in the preceding chaos.

Impact

The tuntian system was to have far-reaching effects, both for Cao Cao himself and for the overall economy of China. Once the scheme had proven successful initially, Cao Cao wasted no time in extending the scheme to all areas under his control; as a result the positive effects of this organised farming was soon felt all over northern China, which he reunified.^{[citation needed]}

In the short-term, meanwhile, the tuntian system was also instrumental to the success of Cao Cao's campaigns, many of which were long-range offensives across the plains of northern China; with a massive and efficient agriculture to support his army, he was able to sustain these offensives and gain victory. Overall, the tuntian system, along with the repair of irrigation works, were among the foremost contributions of Cao Cao to the economy of the Han dynasty, and contributed to the enduring strength of the state of Cao Wei in the Three Kingdoms period.^{[citation needed]}

Taiwan

The Han-led Kingdom of Tungning practiced a variant of the Ming-era tuntian system. The system was established by Koxinga immediately after landing in 1661 to supply his troops. Many places in southwest Taiwan retain their tuntian names.^[9]

Vietnam

The Sino-Vietnamese reading is đồn điền in Vietnamese. During the Nam tiến (March to the South), Khmer and Cham territory was seized and militarily colonised by the Vietnamese. The Nguyen Lords established đồn điền after 1790.^[10]

The South Vietnamese and Communist Vietnamese colonisation of the Central Highlands have been compared to the historic Nam tiến of previous Vietnamese rulers. The South Vietnamese leader Ngo Dinh Diem sponsored colonisation of Northern Vietnamese Catholic refugees on Montagnard land. The now Communist Vietnamese government introduced to the Central Highlands of "New Economic Zones".^[11]

Japan

Tuntian is pronounced tonden as a Sino-Japanese word. It was most notably practiced during the Meiji Restoration in frontier Hokkaido under the name tondenhei ("tonden-soldiers").^[12]

Korea

The Sino-Korean reading of tuntian is dunjeon (or tunjŏn in the North Korean Romanization). Dunjeon was a core part of the Korean military supply and was notable in the following instances:

• During the Qing invasion of Joseon, at Namhansanseong. This system supported a population of 25,000, 10,000 of which were combatants.^[13]
• During the Imjin War, under Yi Sun-sin. He managed dunjeon both as part of his repeated demotion (due to court politics) and on his naval base of Hansando.^[14]
