Zhang Jianfei, a resident of Jilin province in China's northeast, was found guilty in 2010 of endangering public security by stabbing two to death and injuring another 14 on September 17, 2009, state news agency Xinhua reported.
Tourists, security guards and salesmen at roadside shops were among the victims.
Zhang, who used to work at a primary school in Yongji county of Jilin, blamed his actions on his being deeply upset while looking for a job.
He tried to defend himself saying he was drunk at the time of the incident, but forensic doctors concluded following an investigation that Zhang was only slightly drunk and had the full ability to control himself.
Zhang's death penalty was meted out in November 2010.
The verdict was later approved by the Supreme People's Court, as required.
