Back in 2003, a German film crew filming in the Gobi Desert captured an incredibly moving moment: after a tough two-day birth, a mother camel rejected her newborn.
A nomadic family then performed the ancient Hoos singing ritual passed down for generations.
Once the song ended, the camel shed tears and finally accepted her baby.
This powerful scene became one of the most memorable parts of the Oscar-nominated documentary The Story of the Weeping Camel.
