Hi Nerida! Good to know you are in this region - welcome! Yes, holiday time here can make the whole train system go topsy turvy. This year is the first one when the Labour Day holiday has been reduced to 1 day (on May1) from 2 days (May 1 & 2) in previous years. But in China it is common practice to merge a national holiday with a weekend if there is one close at either end. As a result, people are having 3 days off May 1-3 (Thurs - Sat) and resume work on Sunday(!) to compensate for the Friday. So there is a rush on trains, buses and domestic planes because of the long weekend. Sorry your trip timing happened to coincide with this.
Just for people who are planning trips to China, it would be good to know that the main "national" holidays are as follows:
[*]New Year's Day - Jan 1
[*]Spring Festival (Chinese New Year) - Jan-Feb - 1 week to 3 weeks differs from company to company.
[*]Tomb Sweeping Day (Qing Ming Festival) - Mar-Apr - 1 day
[*]May Day - May 1 - 1 day
[*]Dragon Boat Festival - June 7 - 1 day
[*]Mid-Autumn Festival - Sep 15 - 1 day
[*]National Day holiday - Oct 1-3 - 3 days
Just remember that the 1 day holidays can turn into 3 days off when combined with a weekend, and the 3 days National holiday can be turned into a 7 day consecutive break by combining the 2 weekends on either sides with the holiday. For example, Oct 1,2 and 3 are Wed, Thu and Fri this year - so what is inevitably going to happen is that people will work on the Sep 27 and 28 weekend and then take the 29th and 30th off, so that they can then be off work for 7 consecutive days, including the weekend of Oct 4 & 5 at the other end. This kind of thing has until recently been encouraged by the government and has given a great boost to the tourism industry. On the other hand, holiday times prove to be a transportational nightmare for unsuspecting people wanting to take a trip around China at these times. Realizing this, I think, the national holidays have been scattered around different times of the year starting this year.
Most retail businesses do keep open to take advantage of the crowds of holiday makers from remote areas who visit the big cities during this time!
Anyway, I wish you well and hope your trip is successful. Look forward to your photos. Do let me know if you plan to come to the Beijing-Tianjin area - we could plan to meet!
Cheers,
