People usually have anti-theft doors on their houses, but that didn't seem to be enough for one houseowner in Yantai, Shandong province.

A house in a residential community has been installed with three-meter high steel tubes all over.

Anti-theft rails are also built into the windows inside of the house.

The whole house looks like an iron cage and Internet users have called it "the best-anti-theft house".
