What do the three slogans mean?

"Persist in the war of resistance and not surrender", "Persist in unity and not division" and "Persist in progress and not retrogress" 1938 10. After the fall of Wuhan and Guangzhou, War of Resistance against Japanese Aggression entered a stalemate, and the Kuomintang capitulator Wang Jingwei Group publicly defected to the enemy at the end of the year. The Kuomintang die-hards are also vacillating on the issue of the war of resistance. From 65438 to 0939, the Kuomintang regime promulgated the Measures for Restricting the Activities of Alien Parties, which abolished the democratic rights won by the people and the anti-Japanese parties at the beginning of the Anti-Japanese War, and created some anti-friction incidents in some areas, such as the massacre of military and political personnel of the Eighth Route Army. On July 8, in response to the changes in the current situation, the Central Committee of the Communist Party of China published the "Declaration on the Second Anniversary of War of Resistance against Japanese Aggression", proposing "Persist in the War of Resistance to the End-Oppose Midway Compromise!" "Consolidate domestic unity-oppose internal division!" "Strive for national progress-oppose retrogression!" This idea. On September 6th, Mao Zedong summarized these three propositions into three slogans: "Persist in the war of resistance and oppose surrender", "Persist in unity and oppose separatism" and "Persist in progress and oppose retrogression". It shows China's firm stand of resisting Japan to the end for national survival and making unremitting efforts for people's democracy. (
