This is the bizarre moment two chefs demonstrate their extraordinary skills by finely chopping up a slice of potato directly on other people’s backs while blindfolded.

The two men, students at the Hu Zhen Culinary School, in China’s northern Hebei Province, showcased their mastery during one recent class.

Two of their fellow students volunteered to help with the demonstration by rolling up their shirts and bending over, allowing them to use their bare backs as chopping boards.

Then, they put blindfolds on, picked up two giant cleavers, and used them to shred two pieces of potato on their classmates’ backs.

Despite the cutting causing some visible irritation to their classmates’ skin, they were able to finely chop up the vegetables without causing a single injury.

The school later shared the promotional video on Douyin, China’s version of TikTok, leaving many impressed by the two students’ skills.

User ‘Happy medical voice Xiaoxu’ commented: “This has to be absolute trust.”

While user ‘lonely’ wrote: “Are they training their knife skills or are they training their courage?”

And ‘That makes sense, right, right, right’ remarked: “I always chop ribs, stuff dumplings, etc. on my back.”
