GUANGZHOU - A whistleblower is looking for a new job after he blogged about shoddy subway construction in this Guangdong provincial capital.

On Aug 30, two and a half months before the opening of the Guangzhou Asian Games, 69-year-old engineer Zhong Jizhang wrote that the intensity of the concrete used in the construction of the subway's Line 3 northern extension failed to meet national standards.

He further claimed that the concrete's inferiority and possible hazards were intentionally covered up by the contractor.
