China Youth reported that, as part of the military staff cut that Xi Jinping announced last year, China has started the first round of the retirement of officers of the People’s Liberation Army (PLA).
"The 21st Army of the Western Combat Theater, an air-defense unit of the Central Combat Theater, and an armored brigade of the Eastern Combat Theater all have recently held retirement ceremonies for the officers who are leaving the military."
One goal of Xi Jinping’s military reform was to shrink the PLA command structure. "Among the 300,000 military staff cut, half of them are officers."
