The National Day holiday or the Golden Week, one of the country's biggest holidays of the year, was established on Oct 1, 1999. Since then a lot has changed. In the first year, 28 million Chinese went travelling across the nation. This year nearly 600 million took trips during the week long vacation.
Here we walk down memory lane and relive some of the changes during the past two decades.
