Fire Nation Army factory

Located at the shore of the Jang Hui river, this smelting plant is where the Fire Nation army makes the metals for various weapons and vehicles. The cooling system provided by the river water helps in the production of a tough, new armored metal. But as a result, the plant dumps a ton of waste into the river while large smoke stacks simultaneously contaminates the air. But to General Mung, this pollution is a small price to pay for building weapons that can help win the war. It was destroyed by Aang and Katara in The Painted Lady.
