October 1st is China's National Day which commemorates the founding of the People's Republic of China in 1949 (Communist China). There are usually national celebrations and military parades in Tian'anmen Square, Beijing to acknowledge and celebrate the day. National Day is always a week long celebration, October 1–7 and is referred to as ‘Golden Week’. It is the biggest week for tourism in China when people have a week off to visit their families and take trips for the holiday around China and abroad. Because it is a national holiday and China has a big population, this means millions of people travel across China and there are large crowds everywhere during this week.
