Bai Ningyang was a Chinese man who killed 12 people including 3 children in 2006 at a kindergarten after a female teacher rejected his advances. He was detained alive.

The next day, during an extensive search operation involving 800 police officers, Bai was found hiding in a cave in the nearby mountains and arrested. He was sentenced to death and executed.

Two days prior to the attack, on May 6, Bai had a quarrel with a farmer who had stopped him when using a newly paved road. Later that day he armed himself with two knives and chased the man through the village. When his father tried to intervene he took a five-year-old boy hostage, though the child managed to free himself, whereupon Bai ran away.
