Going to China arriving 16th Sep 2019 leaving 5th Oct 2019

The National Day Holiday will start from Oct. 1 to 7. All the sights and shops will open at that time. But it will be especially crowded during that time.

Thankyou for answering my question .it has been very helpfully.
Mrs m Eglinton. 👍👍👍

I would suggest that you travel either before 1 October or after 8 october 2019. This is because 1-7 October (Golden week) is a week long holiday given to people in China specifically so that they can travel.
There are no special festivities at this time (except that you will see the Chinese flag flown alogn some big roads, as the country was founded on 1 October 2019) - but railway stations, tourist spots and bus statiosn are all ultra crowded. Popular tourist spots in Shanghai, Beijing, Hangzhou, Chengdu, Great wall (Chang cheng) also are VERY crowded. So it is not the best time to travel in China. After the holiday however, it becomes much nicer.

1st October to 7th October is National holiday here in China. Will be very crowded at that time.
