On December 2, 1949, the Fourth Session of the Central People's Government Committee accepted the suggestion of the National Committee of the Chinese People's Political Consultative Conference and passed the "Resolution on the National Day of the People's Republic of China," deciding that October 1st, the great day when the People's Republic of China was declared established, would be the National Day of the People's Republic of China. From then on, October 1st each year has also been the birthday of our great motherland.

After the founding of the People's Republic of China on October 1, 1949, the form of celebrating National Day has changed several times.

In the early years of the new China (1950-1959), large-scale celebrations were held every year for National Day, along with military parades. In September 1960, the Central Committee of the Communist Party of China and the State Council decided to reform the National Day system in accordance with the policy of building the country frugally. Since then, from 1960 to 1970, grand gatherings and mass processions were held at Tiananmen Square every National Day, but no military parades were held.

From 1971 to 1983, Beijing celebrated National Day on October 1st each year with large-scale garden parties and other forms, without mass processions. In 1984, during the 35th anniversary of National Day, a grand military parade and mass celebration procession were held. For the following decades, other forms of celebration were used without holding military parades or mass processions. On October 1, 1999, during the 50th anniversary of National Day, a grand military parade and mass celebration procession were held. This was the last grand national celebration of the People's Republic of China in the 20th century.

Since the founding of New China, there have been 13 military parades held on National Day. These include 11 between 1949 and 1959, and two more on the 35th anniversary in 1984 and the 50th anniversary in 1999.

National Day is a characteristic of modern nation-states, emerging alongside the emergence of modern nation-states and becoming increasingly important. It serves as a symbol of an independent country, reflecting the nature of the state and its political system.

Once this special commemorative method becomes a new, nationwide holiday form, it carries the function of reflecting the cohesion of the country and the nation. At the same time, large-scale celebration activities on National Day are also a specific embodiment of the government's mobilization and appeal power.

After the procession, people often gather in parks or public places to celebrate the festival together, singing and drinking joyfully. If it happens to coincide with presidential elections or parliamentary elections, politicians often use this time to deliver campaign speeches. Demonstrating strength, enhancing national confidence, and showcasing cohesion and appeal power are the three basic characteristics of National Day celebrations.
