"The right path in the world is the vicissitudes of life" means: constant variation, constant development, and constant advancement. This is the inevitable law of the development of human society.
Source: From Mao Zedong's "Seven Rules: The People's Liberation Army Occupies Nanjing", "It is better to use the remaining brave men to chase the poor bandits, and not to pretend to be an academic overlord.
If heaven is affectionate, heaven will also grow old, and the world is right. It’s the vicissitudes of life.”
Translation: We should take advantage of this great opportunity when the enemy is declining and we are prosperous to pursue the remaining enemies and liberate the whole of China. Don't imitate Xiang Yu, the overlord of Chu who coveted fame and indulged his enemies, thus causing his own defeat. If nature knew, it would recognize the unchangeable laws of prosperity and decay.

If the sky is affectionate, the sky will also grow old, and the right path in the world is the vicissitudes of life: The last sentence is borrowed from Li He's poem "The Golden Bronze Immortal's Ci Han Song". The original poem says: Legend has it that the extremely valuable gold and bronze immortal statue made during the reign of Emperor Wu of the Han Dynasty was moved from Chang'an to Luoyang by Emperor Wei Ming during the Three Kingdoms period. The meaning of the original sentence is that for such a hateful thing in the world, if heaven is sentimental, it will also grow old due to sadness; here it means that if heaven is sentimental, it will also grow old due to pain when seeing the darkness and cruelty of the reactionary rule of the Kuomintang; those who are oppressed by the reactionaries It is natural for the people to completely overthrow the reactionary rule and complete the earth-shaking revolutionary cause.
