The first time I posted about the Tianjin explosion, the government wasn’t giving any info. on the cause(s) of the accident. The death toll rose over 100 and lots of people are injured. China has also experienced structural problems in the past from contractors who cut corners in terms of regulation. Moreover, the overall number of accidents, death tolls, and injuries (from accidents) have been declining in China.
In this article from the NY Times, the owner of the warehouses admitted fault to the public, and the government will investigate and punish those who were involved to allow these warehouses to operate when they violated regulations. You will realize how important social networks are to get you what you want/need in China. Visit the source to see another image and a graphic!
