You never know what day is going to be your last, and when you're young, you don't think about it too much.
One girl's night out with friends on Christmas ended abruptly when she collapsed and was rushed to an emergency room.
A 28-year-old marketing consultant and part-time model had no known medical conditions before she suffered a brain hemorrhage and died three days later in hospital.
Brain hemorrhages usually occur in individuals who have untreated high blood pressure, and when the blood vessel walls weaken, it swells, causing it to pop and bleed into the brain, which leads to a stroke.
Chinese media reported that her brain started bleeding after reaching a singing pitch that was too high, but experts believe that wasn't the case.
This shocking news has devastated the young woman's family, who are now looking for clues to understanding their daughter's untimely death.
