A set of railings in south east China’s Jiangxi province has crumbled, revealing a core of cheap foam around an outer layer of cement.

Situated alongside Pencheng Road in the city of Ruichang, the 400-metre barrier was built in 2012 but is already falling apart after just three years.

According to state media reports, the material is “highly flammable.”

Internet users denounced the construction work as a “tofu-dreg project”—a term often used in mainland China to describe a poorly built structure.

Where the barrier has been falling apart, however, local authorities have stepped in with yet another quick and cost-effect solution: gluing it back together.

In a similar incident last month, parts of an up-scale residential development in Shaanxi province was also found to be constructed from foam, prompting an outcry from residents.
