Baffled shoppers in a Chinese city couldn't work out where the snoring noise was coming from until they looked up.
And there - 20ft above them - was a homeless women curled up and fast asleep perched on a narrow tree branch.
Passers-by, in Lanzhou, Gansu province, couldn't believe the woman was able to sleep in her precarious position.
"We wouldn't have known where the snoring was coming from except one of her shoes fell off and hit someone on the head," said one shopper.
Police eventually persuaded her to come down to earth with sandwiches and a bottle of water.
