A bizarre video has emerged from China of a 74-year-old barber straightening a woman's hair with hot tongs.

The footage, captured in Mianyang, Sichuan Province on April 11, shows the barber called Wang Weimei using a pair of hot tongs to style the hair for a customer.

It used to be a popular traditional way to style hair in China, but it almost lost now.

This method reportedly means the hair will remain straight for at least three months.
