A stabbing spree in China's eastern city of Yixing left eight people dead on Saturday, police said in a statement. Another 17 were injured.
The attack took place at the Wuxi Vocational Institute of Art and Technology in Jiangsu province.
The authorities identified the suspect as a 21-year-old student.
The AFP news agency cited police as saying he has been arrested.
The student was meant to graduate this year but had failed his exams.
"He returned to the school to express his anger and commit these murders," police said in a statement, adding that he had confessed to the crimes.
Police said emergency services were fully mobilized to treat the wounded, and provide follow-up care for those affected by the attack.
The incident comes just days following a hit-and-run incident where thirty-five people were killed and 43 others were injured after a car drove into a group of people outside a sports center in the southern city of Zhuhai.
And there has been a spate of other attacks in recent months. In October, a man killed three people and wounded 15 others in a knife attack at a Shanghai supermarket.
And the month before, a Japanese schoolboy was fatally stabbed in the southern city of Shenzhen, which borders Hong Kong.
