Nan Shan River

The Nan Shan River is a small river located in the southern Earth Kingdom. Though the current is very strong in some places, in others the water forms in calm pools and streams, making them ideal for bathing - or washing a sky bison. A duel between Katara, Sokka, Mai and Ty Lee took place by the river.

History
Not much is known about the early uses of the river, but it was likely utilized as a source of food or water to the people who lived in the nearby town of Tu Zin before its abandonment.

Due to Appa's shedding of his thick coat of fur, Princess Azula and her allies were given an easy trail to follow when they tracked Team Avatar. Upon arriving at this river, Toph discovered the hairy trail Appa was leaving and alerted the others. After a quarrel with Aang and Katara, the earthbender angrily gathered her belongings and left the group to clean up Appa themselves. Aang and Katara used their waterbending to bend the water of the river atop Appa, while Sokka was knee deep in the river brushing the bison's head. After his bath, Aang took some of Appa's shed fur and spread it out to leave a fake trail to divert Princess Azula. The river, however, was filled with clumps of Appa's fur, enabling Azula to see through their charade.



While Azula followed Aang's trail to the deserted town of Tu Zin, Mai and Ty Lee pursued Appa, Katara, and Sokka up the Nan Shan river. The threesome tried their best to escape the two girls riding their mongoose dragons. After Appa managed to cross the river before crashing, the Water Tribe siblings momentarily thought they were safe before realizing otherwise. Azula's allies forded the river on their mounts, and a short duel was fought. Mai was able to pin Katara to a tree, and Ty Lee easily paralyzed Sokka using chi blocking. When Mai prepared herself to finish the fight, Appa butted in and airbent the Fire Nation women into the river. Both girls were washed ashore downstream.
