The fire occurred on Monday at a building under renovation. Previous reports put the toll at at least eight dead and more than 90 injured.
A witness told Xinhua that building materials had caught fire, and the blaze spread to scaffolding and then to the 28-story building itself, which houses a number of retired teachers.
The government says more than 80 fire trucks were called to battle the fire, which appeared to have been put out after about six hours.
