Struggle is the spiritual pedigree and fine style of the Chinese nation, Chinese people and members of the Communist Party of China (CPC). The Report of The 20th CPC National Congress has proposed for more than once continuous struggle, hard struggle and united struggle. Deeply understanding the historical process, its spiritual connotation, and the great significance of the great struggle, and grasping the fundamental requirements of persisting in continuous struggle, hard struggle and united struggle will provide the ideological basis and theoretical support for us to better explain the struggle in theoretical innovation, carry out the struggle in practice, and unswervingly implement the tasks and objectives put forward by The 20th CPC National Congress .
