On October 21, 2015, the Chinese publication Caixin quoted an official PLA website as reporting that 66-year old retired academician PLA Major General Zhou Guotai, who was formerly Deputy Head in charge of fuel and supplies at the PLA's General Logistics Department and is a Fellow of the Chinese Academy of Engineering, was being investigated on charges of corruption. Zhou Guotai was once hailed as the "Father of China's bullet-proof vest".
