What is the origin of National Day?

The Fourth of July, also known as National Day and National Day of Remembrance, is a legal holiday instituted by a country to commemorate the country itself, usually the anniversary of the country's independence, the signing of its constitution, or other significant anniversaries. On this day, each country holds a variety of celebrations. In ancient China, the emperor's accession to the throne and his birth were called "national celebrations".

The term "National Day" originally referred to national celebrations. It was first used in the Western Jin Dynasty. Western Jin Dynasty writer Lu Ji in the "five vassals" in an article had "national celebration of its own benefit, the main worry and its harm" record. China's feudal era, the country celebrates the big event, no more than the emperor's ascension to the throne, the birth (the Qing dynasty called the emperor's birthday for the festival of long-lasting), and so on, and therefore the ancient China to the emperor's ascension to the throne, the birth of the emperor is called the "National Day", and today called the anniversary of the establishment of the country for the National Day.

New China National Day refers specifically to the anniversary of the official establishment of the Chinese People's Republic of China, so people across the country will be celebrated on October 1 every year.
