Frozen waterfall in China
If you think it's cold where you are, then spare a thought for people in eastern China - the weather's so chilly there it's frozen a waterfall!
Tourists have been flocking to see the unusual sight in Shandong province.
The waterfall is about 100 metres long and there are large open areas behind the ice curtains where people can walk around.
"It's like an ice palace. It's magical," said tourist Chen Wenxia.
