In China, the National Holiday is a big deal and it is to celebrate the founding of the People's Republic of China by Mao Zedong in 1949.
Besides from the Spring Festival, the National Holiday is the only other week-long public break from school and work.
Due to the alignment of the lunar and solar calenders, this year, the Mid-Autumn Festival holiday came immediately before the National Holiday creating a 'Golden Week'.
As one of the only opportunities available for workers to go home, visit their families or to travel around the country, all hotels, tourist attractions, trains, buses and aeroplanes around the country are completely packed with holidaying Chinese people.
On Weibo, the photo on the right of Shanghai's famous Nanjing Dong Road pedestrian street taken during the National Holiday (note all the China national flags) has been spread around many times.
Out of interest, our Shanghai school is just 2 streets away on the left of this photo.
