Fake or real?

It is almost certainly fake but footage of a mirage city appearing in the clouds above China has caused a stir on social media.

In the video, captured in Guangdong Province earlier this month, buildings can be seen hiding among the clouds.

The phenomenon became a hot topic after the video was posted on social media and was even broadcast on local TV stations.

However, no eye witnesses or other pictures were found to exist, leaving a lot of doubt about the veracity of the footage.

Some experts also rejected the possibility of a mirage, considering the weather conditions at the time, according to news reports.
