China probes personal disputes after mass killings. Many fear further infringement on freedoms

China's leader Xi Jinping wants the recent spree of mass killings that shocked the country not to happen again and has ordered local governments to prevent future 'extreme cases.'

The order came from the top.

China's leader Xi Jinping wants the recent spree of mass killings that shocked the country not to happen again. He ordered local governments to prevent future "extreme cases."

The attacks, where drivers mow down people on foot or knife-wielding assailants stab multiple victims, are not new in China. But the latest surge drew attention.

Local officials were quick to vow to examine all sorts of personal disputes that could trigger aggression, from marital troubles to disagreements over inheritance.

However, the increasing reach into people's private lives raises concerns at a time when the Chinese state has already tightened its grip over all social and political aspects in the East Asian nation.

This is how people in China label these attacks.

In November alone, three took place: A man struck people at an elementary school in Hunan province, wounding 30, after suffering investment losses. A student who failed his examination stabbed and killed eight at a vocational school in the city of Yixing. The most victims, 35 people, resulted from a man mowing down a crowd in the southern city of Zhuhai, supposedly upset over his divorce.
