Born at a time of domestic turmoil and foreign aggression,the Communist Party of China(CPC)has an ingrained understanding of and has always attached great importance to national security.Undergoing different stages of national development from“standing up”to“growing rich”and to“becoming strong,”the CPC has been constantly adjusting its visions and strategies on national security in light of changes in the international situation.Such visions and strategies will surely continue to be enriched and improved in the great endeavors of building socialism with Chinese characteristics.With the proposal of the“ten upholds,”the theoretical system of national security with Chinese characteristics for the new era has taken shape,which will be underpinned by a holistic approach to national security.Thus,a historic leap in the century-old construction of the CPC\'s national security theory system has been achieved.This paper aims to explore the ideological context of the formation and development of a holistic approach to national security from the centennial evolution of the CPC\'s national security thought,comprehend the theoretical guiding role of the CPC\'s national security thought from China\'s historic achievements over the past century,and grasp the historic significance and values of upholding and developing a holistic approach to national security from the new historic juncture in China\'s development and its historical responsibilities in the context of great changes unseen in a century.
