To celebrate the 70th anniversary of the founding of the People's Republic of China (PRC) and present a panoramic view of the country's great journey, the 24-episode documentary "On the Road" focuses on the great achievements and valuable experiences of people of all ethnic groups in the socialist revolution, construction and reform over the past 70 years. It also recounts the touching stories and important events of the country since 1949.

The third episode of the series is centered on how China established its political and economic systems.

The Communist Party of China held the Third Plenary Session of its Seventh Central Committee from June 6 to 9, 1950, in Beijing. The meeting mainly discussed economic issues. This was a clear indication that the party's focus was shifting from revolution to economic development. 

On June 25, 1950, the Korean War broke out. The U.S. dispatched forces to the frontline and sent its Seventh Fleet into the Taiwan Strait. On October 8, Mao Zedong ordered the formation of the Chinese People's Volunteer Army. During the night of October 19, the Volunteer Army crossed the Yalu River and entered the war. 

Between October 25, 1950, and June 10 the following year, the Chinese and DPRK forces, through a series of successful engagements, steadily pushed the American-led army back. The victory of the war had defended New China, safeguarded world peace, and guaranteed conditions for economic construction to progress at home. 

On June 15, 1953, Mao Zedong proposed a general line for the coming period of transition. And so, the whole country embarked on the three major transformation movements. 

By adopting the Constitution and establishing the political system of the People's Congress in 1954, China laid a solid foundation for further development and prosperity.
