Happy National day

National Day is a statutory holiday established by a country to commemorate the country itself.

They are usually the independence of the country, the signing of the constitution, the birthday of the head of state or other anniversaries of great commemorative significance; some are also Saints' Day, the patron saint of the country.

Although most countries have similar anniversaries, due to complex political relations, this holiday in some countries cannot be called National Day. For example, the United States only has Independence Day and no National Day, but the two have the same meaning.

In ancient China, the emperor's enthronement and birthday were called "National Day".

Today, China's National Day refers specifically to October 1, the anniversary of the official founding of the People's Republic of China.
