A man in eastern China decided to show off to his son-in-law after getting a little drunk and smashed a thick brick with his head.

The son-in-law – named Mr Gao in local media in Qingdao, Shandong Province- said he had brought his family to visit the old man over New Year’s.

He said all the family members were having a fun holiday celebration, chatting and drinking on the night of 2nd January.

When talking about the past, the father-in-law boasted about having practised Iron Head Kung Fu, as he was a little drunk at the time, Mr Gao said.

He insisted on giving them a performance with a brick, so he picked up two bricks outside the small courtyard, wanting to smash them in one go.

Mr Gao filmed his father-in-law as he set out to perform a remarkable show-off.

In the video, the old man can be seen doing a set of preparatory movements, after which he swung the brick at his head and amazingly – smashed the brick in half with just one strike.

Iron head training, or Iron Head Kung Fu, namely consists of strengthening the skull’s bone structure to build its resistance against impact.

In addition, the dangerous yet impressive technique makes one’s skull so strong that it can also be efficiently used as a weapon, and can shatter bricks with ease.
