My Chinese skills are pretty much to zero so here is what I understood. The guy who’s trying to jump off the roof was working in a factory and his boss did not pay him for his work. He came back one night to get what was due to him and was beaten instead, so he went on the roof to commit a suicide. But luckily, a woman convinced him not to jump by begging him and kneeling on the ground. Now there is an investigation.
