That's so annoying when dates are not fixed and you just cannot get on with getting on with stuff. Just keep making lists, that's usually what I do when I can't actually make things move forward myself. At least it feels like I'm doing something then.
Great that you will be able to get over here soon and have a proper look around for yourself. Helps to see it all with your own eyes and get a feel for the place and where you would find it comfortable.
Easter holidays are not too long here, usually only a week for most schools as the schools have to juggle with local national holidays as well as our standard holidays. My DDs seem to always be having days off here and there most months.
Been thinking about other things to bring over and have come up with decent tea bags if you like a brew. Really daft when you're moving to THE country of tea, but tea here isn't the same and the wishy washy lipton tea bags that you can fine in the shops just do not make for a decent cuppa. I actually get my Dad to supply PG tips to us.
Good point for the school shoes. Quite hard to find decent ones here. I tend to buy when back in Europe during the summer. Sports stuff and trainers are OK though and there is a decent sports shop chain here from France (Decathlon) which is not pricey and where you can stock up on cheap T shirts, fleeces, sports socks and the like.
For children's clothes, we also have a couple of good brand shops (again from France) Okaïdi in the Carrefour store shopping gallery and Orchestra on Huai Hai Road (main shopping street in town centre), then there's GAP, H&M, UniQlo and there is an underground market selling kid's clothes and things where you can pick up bargains on basics and can haggle a bit.
What's cheap ? Not a lot if you only buy imported stuff. If you go to local markets for veg and stuff, then that's cheap (be careful for the quality).
There's also a huge market in QiPu Road (actually high rise warehouse places) where you can get lost for a few days and can find cheap clothing, shoes, trinkets, bags etc - great fun, you can bargain but need to check quality. There are also some of these behind the city centre ancient garden (Yu Garden) where you can pick up all sorts.
Its also not too expensive to get clothes made in either of the clothing markets in town. Loads of stalls where you can take favorite pieces and get them copied or pick from designs on show, choose your material...
Eating out is not too pricey, if you go local and avoid the posh, trendy places where prices are similar to home. We tend to eat out loads here compared to back home.
Public transportation (taxis, buses and underground) is really low priced, so getting around the city is easy and cheap. The underground is simple to use and well signposted in English. Taxi drivers don't usually speak English, so useful at first to have places written down in chinese, until you get the hang of it.
Another thing to slip into your luggage, which we have found useful with children has been a decent yogurt maker. Ours eat loads of the stuff and the range here is really limited and quite pricey. Maybe not useful if you're not into dairy.
But most of all, it is a big city where you can find everything (well almost everything) so don't worry too much and enjoy.
