At 7:30 PM on the fifth day of the first month of the lunar ox year, which was January 30, 2009 in the Gregorian calendar, an explosion at No. 19 Dongnanan Road in Yuexiu District, Guangzhou, drew attention from all sides. From the day of the incident to yesterday, for a full six days, the media throughout Guangzhou continuously replayed and reported on the event repeatedly. The focus of attention shifted from the mobile phone to the battery, then from explosives to a homemade triggering device. Without any authoritative statement, these various claims and uncertain speculations were exceptionally fragile, almost all having a lifespan of only one day before being successively denied on the second day or not long after. The exact truth remains questionable.
