Jang Hui River

The Jang Hui River is a river in the eastern Fire Nation. The village of Jang Hui is actually located on the river, and a factory making supplies for the Fire Nation Army was once located beside the river.

The Jang Hui River was one of the most beautiful rivers in the Fire Nation. However, during the War, a factory was built near the river, and pollutants were constantly dumped into it. This caused pollution in the waters of Jang Hui. Illnesses developed among the locals and wildlife was killed or mutated. The entire ecosystem was in shambles. It was this polluting of the river which drove the Painted Lady, whom was protecting it, away, leaving the people living nearby to fend for themselves. Aang and his friends came to Jang Hui and saw the damage which the factory was causing. Katara and Aang later destroyed the factory, and after the residents of the town cleaned the river, the natural splendor of the Jang Hui River and the health of its environs were restored almost immediately.
