Due to the wrong leadership of left adventurism, the Red Army failed in its fifth counter-campaign against "encirclement and suppression". Where is the China Revolution going? Should we stick to the established policy and fight to the end, or should we re-plan and do something else? The CPC Central Committee summed up the experience and lessons in time, voluntarily abandoned the base areas, led the strategic shift of the Red Army of Workers and Peasants, and shocked the world with the 25,000-mile long March, which made the China revolution get rid of the crisis and embark on the smooth road to victory.

Producers in China adjusted their strategies in time and held high the banner of reform, so the people of China quickly embarked on a road of enriching the people and strengthening the country.

Einstein was born in the era of rapid changes in physics, and a series of physical phenomena that are difficult to explain in classical physics theory have appeared one after another.

There was a college student who entered an enterprise after graduation and became a porter. His salary is similar to that of migrant workers of the same age. He used to be the darling of society, the son of heaven, but it was "rare" to step into society. He was unhappy and miserable, and thought of death several times. After several struggles, he thought, I have been a farmer for generations, so consider myself a migrant worker who doesn't study. So I worked hard for five years a year, from porter to porter, gained the trust of leaders and was promoted to deputy general manager. He said, "If it hadn't been for that ideological turn, maybe I would have left this world long ago."

Turning around is not giving up, not giving in. Turning around is another kind of enterprising, more active and effective enterprising. When we encounter obstacles on our way forward, we should learn to turn back to succeed.
