Classes resumed on Wednesday at a local primary school where a man stabbed eight children to death on Tuesday, but some shocked students remained at home, while psychologists try to help traumatized students process their pain.

At 7 am, many students arrived, escorted by family members, and began to enter the Nanping Experimental Primary School.

Previously, the gate opened at 7:30 am sharp and pupils who arrived early had to wait outside.

"If the children had been allowed to enter the school grounds upon their arrival, before the school's opening time, the tragedy might have been averted, or at least have resulted in fewer deaths," said Jiang Wenming.

He burnt incense on the site in memory of first-grader Chen Chuning of his family. The 9-year-old girl died in the killing spree, which happened at 7:20 am on Tuesday.

She was among the other young victims who crowded outside the school gate waiting to be allowed inside, Jiang told China Daily on Wednesday.

Five other children were injured in the attack.

Young witnesses who survived the incident were struggling with the trauma, relatives said.

"My 10-year-old granddaughter cannot forget the scene when her schoolmates fell down in blood right in front of her. She refused to come to class today no matter what," said an elderly woman, who declined to be named.

To help address the trauma, school authorities dispatched teachers to the gate to welcome students. At 8:12 am, more than 2,000 students and members of the school faculty presented white flowers to the victims' families.

School officials arranged for professional psychologists from various parts of Fujian to visit each class, to talk to students and show them how to cope with the negative impact and stress of the attacks.

Xiong Fuxian, a psychiatrist with a local hospital, said the mental health interventions were carried out in varied forms according to the students' needs.

For the younger ones, who are more resilient, games were organized to bring them happiness and a sense of safety under sound protection, he said.
