Xinhua carried a news article that China Review News had originally published reporting that 600,000 people in China die from overwork or Karōshi each year, which is an average of 1,600 people a day. This number is the highest in the world and even surpasses Japan. Most of them are young professionals; they die from cardio-cerebrovascular disease symptoms. Work pressure, over-exhaustion, and stress are the main contributors to the cause of death. Close to 70 percent of the people born in the 1980s claim they feel overworked.
