SHIJIAZHUANG, March 29 (Xinhua) -- A Chinese military leader has urged the army to learn and implement the strategic layout of the "Four Comprehensives" put forward by President Xi Jinping and improve ideological and political work.

During an inspection trip to the People's Liberation Army troops in Hebei and Shanxi provinces, Vice Chairman of the Central Military Commission (CMC) Xu Qiliang said learning and implementing the "Four Comprehensives" is a major political task for the army.

The negative impact of the corruption case of Xu Caihou, a former CMC vice chairman, must be cleared up, he added.

Xu also urged the army to study CMC chairman Xi Jinping's speeches on national defence and military building and to resolutely follow the central leadership and Xi.
