What is the Earth Kingdom town where Toph's family lives?

The Earth Kingdom town where Toph's family lives is Gaoling. Toph Beifong is born into the wealthy Beifong family, whose home is in Gaoling, an Earth Kingdom settlement associated with her privileged upbringing.

Toph's parents, Lao and Poppy Beifong, are extremely protective because Toph is blind. They misunderstand her abilities and treat her as fragile, unaware that she secretly trains as an earthbender with badgermoles, the original earthbending practitioners. Her remarkable seismic sense lets her read vibrations through the ground, giving her an unusual way to perceive the world.

Toph eventually competes in Gaoling's Earth Rumble tournament under the alias the Blind Bandit. She becomes its undefeated champion, reportedly holding a 42–0 record, before meeting Aang and his friends. A common mix-up is confusing Gaoling with Omashu or Ba Sing Se, two much larger and more prominent Earth Kingdom cities. Gaoling is important because it is both Toph's home and the setting where her secret identity as a champion is revealed.
