Four of the blaze victims, who have received intensive hospital care for the past five months, are not expected to go back to school until next year.
Professor Walter King Wing-keung, head of the Prince of Wales Hospital's burns unit, said they could leave the hospital in a month if they were able to walk steadily.
'Their burn wounds have all been covered [with skin grafts]. Now our major job is to help them walk and cure the burn scars,' he said.
'In the next two years they will have to undergo a series of reconstructive surgeries on their faces and hands. I believe all of them can go back to school next year.
'Their appearances might have changed, but I think their insides are still the same. I hope they can live very bravely from now on.' So Yuen-shan, 13, Chan Chor-man, 14, Chong Mei-yee, 13, and Cheung Yun-hang, 13, have been in the hospital's intensive care and burns unit since the hill fire in February.
Schoolmates Chan Wai-hung, 13 and Lee Chun-man, 13, who were both discharged, plan to go back to school in September.
