1. A deadly fire swept through a Hong Kong apartment complex last week, claiming at least 151 lives and leaving over 30 people missing. The complex was undergoing renovation since last year.

2. Residents have alleged that they repeatedly conveyed concerns about the use of flammable materials in the renovation work to authorities, but no action was taken. Authorities suggest that flammable foam boards used in the project may have contributed to the rapid spread of the fire.

3. An architect involved with the residents' case stated that, given the fire concerns, authorities should have replaced the materials in accordance with laws. The Hong Kong chief secretary acknowledged issues with the construction company using substandard materials in hard-to-reach areas but did not address the residents' criticism of the government's approach to the issue.
