History

In historical contexts the lake is sometimes known according to its Japanese pronunciation, as the Chōshin Reservoir.^[3] (Most likely the Japanese pronunciation of the Korean name, for the actual Kanji; 長津湖, is read out as Nagatsu mizuumi). In 1950 it was the site of a major battle of the Korean War, the Battle of Chosin Reservoir, in which the Chinese People's Volunteer Army stopped the northward advance of the United Nations allied forces, but paid a heavy price in casualties.

Economy

Changjin produces large amounts of lumber, and leads the province in mine production. Deposits of silver, graphite, jade, and gold are found in the area. Local agriculture is dominated by livestock raising and dry-field farming; local crops include potatoes, barley, soybeans, red beans, maize, and oats.

Jangjin has a hydropower station on the Jangjin river with its construction goals being completed during the 80-day campaign for the 8th congress of the WPK.^[4]

Transportation

Although it could long be reached only by horse or automobile, the construction of a power plant on the Changjin River also brought the Changjin Line of the Korean State Railway to the county. Water transportation also developed thanks to the power station.
