A train commuter went to extreme lengths to keep her valuables by her side during a security check at a station in China, when she climbed into an X-ray machine to be near her handbag.

The woman's bizarre actions startled security officers at the Dongguan Railway Station in China's southern Guangdong province on Sunday (Feb 11), according to Chinese media.

A video shared online showed the woman placing her luggage on the conveyor belt of the machine, before walking through the security scanner with a small handbag.

When told that all her valuables would have to pass through the machine, she turned around and was seen hopping onto the conveyor belt as well.

Two X-ray images showed a silhouette of the woman, still in her high heels, kneeling on all fours behind her belongings.

Security camera footage then showed her climbing out of the machine and checking her handbag and luggage, before walking away nonchalantly.

It is not clear what the woman was carrying in her handbag.

Local media reported that Dongguan Railway Station staff have advised passengers not to ride the X-ray machines, as radiation given off by the scanners could be harmful.

The unusual incident happened amid the world's largest annual human migration, as millions of Chinese return to their home towns for the Chinese New Year, which falls on Feb 16.
