To be honest, this isn't surprising coming from China. Lets face reality, their own citizens only know what China whats them to know, many of the China citizens don't even know about some major disasters and attacks on China.
While it may seem silly to many, this is the type of country these people live in; to many of them its a norm. and widely accepted. Whilst to us it seems like a unjust act of "parental control" over the Chinese government. I personally find it over kill to remove such a small incident.
