What to wear to York, England from late September to April?
If you have daily necessities, you can bring some, and if there are many things, just bring some basics. Toothpaste, soap and the like are just enough for just now. These are easy to buy, but they are a little more expensive than in China.
If you smoke, bring more yourself. It's expensive here. Of course, the law stipulates that only two can be brought, and the customs will check.
I don't quite agree with LS about diet. Cooking by yourself is still very important. Foreigners' meals will be disgusting after two days. You can't eat it every day in China restaurant. Boring and unhealthy. Food in Britain is expensive, but it's cheaper than eating out. Where else can I take my meals to study abroad? It's so far and heavy. Go buy it.
PS if you don't enter from London, don't worry about customs. Usually no one checks.
Oh, you're here for a master's degree, right? I don't need a flashlight. I've never used it. Shoes and clothes are easy to buy, and the sizes are all right. If you stay for a year, don't bring too much. Finally, you can't take them back and throw them all away. The suggestion is to go home during the Christmas holiday, and there is nothing to do and no place to play there in winter. If you find something missing, you can go home and get it. After all, you will have to stay for a long time. If Easter comes, the weather will be much better and more suitable for going out to play, whether in Britain or Europe. It's a waste to go back.
