to preliminary investigations by the police, the man was trying to commit suicide on Friday, due to family problems.
According to the state broadcaster China Central TV
who filmed the incident, when the man threatened to commit suicide, China's regimental police and fire fighters rushed to the scene.
The rescue operation was stopped several times when the man threatened to jump. Finally, in the CCTV video above, one policeman distracted the man by speaking to him through a loudspeaker while other policemen climbed up to the roof.
One of the policemen then swung around the building on a rope, grabbed the man and took him to safety.
