TU-YN

Pinyin Duyun, city in central Kweichow sheng (province), China. Situated some 60 miles (100 km) southeast of the provincial capital of Kuei-yang, Tu-yn is a transport centre, with a highway route running eastward into Hunan province and a main route, followed by a highway and railway, running south to Liu-chou in Kwangsi province. It is approximately 25 miles (40 km) south by rail from the junction of a line running eastward from Kweichow to Hunan. The north-south railway, begun during World War II and completed as far as Tu-shan (south of Tu-yn) by 1944, was destroyed in the last stages of the war but was rebuilt in the mid-1950s. Tu-yn subsequently became the economic centre of a large district, which has been considerably developed. There is some small-scale coal mining, and paper, linen textiles, leather, and other goods are produced. In the 1960s a chemical industry, producing large quantities of fertilizers, was developed. Pop. (1990) 132,971.
