The black boxes from the China Eastern Airlines plane crash have been found, according to Chinese state media.
Technical equipment on airplanes can reveal reasons for a crash.
State media said that the box was damaged, but it was not clear if it was the one that recorded flight data or cockpit communications.
A Boeing plane carrying 132 people nosedived in a rural, mountainous part of the southern region. Authorities haven't confirmed any deaths or shared why the crash happened.
