One also has to wonder how much of the purported damage at Wenchang is due to deficiencies in build quality of PRC space launch infrastructure. The PRC has long spent a great deal on infrastructure of all kinds as a way to boost its GDP, but a lot of it is apparently of questionable quality. Rail and roadway bridges have collapsed with some frequency and so have entire apartment blocks. There has even arisen a pejorative phrase to describe this type of sub-par corner-cut construction – tofu dreg, as though the stuff was built with bean curd instead of concrete.
