Six people including the driver were rescued and hospitalized, Sun Jun, deputy director of the local government information office, told CNN.
The number of fatalities is an initial report, according to state-run CCTV.
"The fire was so big that some bodies were burned beyond recognition -- and the death toll is being tallied," Sun said.
It was unclear what caused the fire and an investigation is under way.
