[Ming Pao Special News] Hongfuyuan Maintenance Contractor changed the fire escalator window into a wooden "raw entrance", which caused the smoke to enter during the fire. Rong Zhaolun, senior building maintenance surveyor of the Independent Review Unit (ICU) of the Housing Bureau, admitted at the hearing yesterday that he had randomly checked the window replacement project application form in May last year and personally reviewed the photo of the raw entrance for approval, but at that time, he felt that the change was only a temporary protection for the rotten window. After the fire, he knew that there were workers in and out.
