A 30 mm precipitation was reported that day, which might have led to the perlite absorbing a large amount of water and resulting in the roof's overloading and collapse.

[1] Wuhan’s official newspaper, the Changjiang Daily, on the other hand, urged the local authorities in Qiqihar to investigate whether the collapsed building was a ‘tofu-dreg project’ in the first place.

[18] Sources of social media in mainland China claimed that a large number of police officers[10][19] were deployed to gather the parents of the victims and kept them under watch while sharing little to no information with them.

[9] A video circulated on the internet has shown a devastated father claiming they were not updated with information for the first five to six hours, and they were not allowed to identify their children’s bodies.

The claim was echoed by other parents in the video, as well as users of social platforms, criticising the lack of proper communication from the police officers, the local officials, the school, and the hospital.
