Long Yun (; 27 November 1884 – 27 June 1962) was governor and warlord of the Chinese province of Yunnan from 1927 to October 1945, when he was overthrown in a coup (known as "The Kunming Incident") by Du Yuming under the order of Chiang Kai-shek.
Early life
Long Yun was an ethnic Yi, and a grandson of a tribal headman (tusi). His Yi name was Naji Niaoti (纳吉鸟梯) or Naji Jiajia (纳吉岬岬), while Long Yun was a Han Chinese name he adopted later. He was a cousin of Lu Han.
Long Yun participated in the anti-Qing struggle in its early years. First he joined the local warlord's army in 1911 and was gradually promoted to the rank of corps commander. He served in Tang Jiyao's Yunnan Army for years until February 1927, when he, together with Hu Ruoyu, launched a coup and expelled Tang from office. Soon after that he became 38th Army commander in the National Revolutionary Army, at the same time continuing as Yunnan chairman for more than a decade.
Governor of Yunnan
After the remarkable "26" coup, Tang Jiyao, then governor of Yunnan, was overthrown by Long Yun and his allies. Long Yun succeeded as the new governor and served as governor of Yunnan from 1928-45. When he was in power he put forward the goal of building a new Yunnan. He carried out a series of reorganizations and reforms from political, military, economic, cultural and educational aspects. During this period Yunnan was politically clear, had good social stability and a strong atmosphere of democracy. He consolidated and reorganized the economy, expanded paper money in the region and reorganized the tariff tax regulations. He prioritized textile export while reorganizing and developing production of tin ore, tungsten, antimonies, copper, salt, coal and other resources. Another big part of his project was the improvement of infrastructure, which was very poor in Yunnan. To improve it, he established a transportation enterprise that built the Yunnan-Burma Highway, the Diankang Road, the Sichuan-Yunnan West Road, the Yunnan-Sichuan Road, the Yunnan-Guangxi Highway and the Diankang Highway. He also paid much attention to the agricultural parts of Yunnan. He implemented measuring of land and later used the information they achieved to put through a reformed tax collection. He worked to expand grain farming, reduce tax revenue and strived to achieve food self-sufficiency for all farmers. Due to Long Yun's reforms, Kunming (capital of Yunnan) was commonly known as a "democratic fortress".
Second Sino-Japanese War
He was nominated as commander-in-chief of the 1st Army Group, fighting against the Japanese in his province. The Second Sino-Japanese War (1937–45) brought progress and modernization to Yunnan, as the Nationalist government developed the province into a war base against the Japanese. Factories, universities and government agencies were transplanted there from the coastal regions, and fresh manpower, capital and ideas poured into the province. Industries were established and efforts made by the government to develop the resources of the region. The Burma Road made Yunnan the corridor through which supplies flowed to Allied bases in all parts of China, and Kunming became a key U.S. Air Force base. A major advance by the Japanese Army along the upper Salween River in 1942 was halted at Huitongqiao, near Tengchong, indicating the vital role that Yunnan played in the country’s defense.
The campaign involved Chinese troops, assisted by American forces, crossing the upper Salween on 11 May 1944 in order to drive Japanese forces from Yunnan into northern Burma. On 11 May about 40,000 Chinese of the Chinese Expeditionary Force crossed the Salween initially and a further 60,000 arrived later. About 17,000–19,000 Chinese and 15,000 Japanese were killed in the resulting battle. There were more Chinese casualties because the Japanese had time to prepare their fortifications on the south side of the river.
