A controversy over a waterfall has cascaded into a social media storm in China, even prompting an explanation from the water body itself.
A hiker posted a video that showed the flow of water from Yuntai Mountain Waterfall - billed as China's tallest uninterrupted waterfall - was coming from a pipe built high into the rock face.
The clip has been liked more than 70,000 times since it was first posted on Monday.
Operators of the Yuntai tourism park said that they made the "small enhancement" during the dry season so visitors would feel that their trip had been worthwhile.
"The one about how I went through all the hardship to the source of Yuntai Waterfall only to see a pipe," the caption of the video posted by user "Farisvov" reads.
Now that we know how to build a water fall from scratch, it's just a matter of time until the world record of the highest water fall will be in Saudi Arabia or Quatar...
"The world's largest waterfall is fed by the world's second-biggest pump. The world's biggest pump is used for the air conditioning that keeps the surrounding forest at a pleasant 20°C cooler than natural temperatures."
