Don’t forget to bring one or two power supply changeover devices for German model because in Germany there is impossible to find them for your Chinese electronic devices such as notebook, mobile phone or your digital camera if you need to charge up immediately. You can find them in the big super markets of any big city in China or you can search and buy them online like through 360buy.com (http://www.360buy.com) etc.
There is normally no pajama, no toothbrush, no comb and even no slipper at a German hotel, so you had better not forget to bring your personal belongings before you set off.
If you come to Germany for a while like a 3 months exchanged study, you can also bring some dried food or cook devices what you are habited to eat or use at home such as some tee or a rice cooker. Owing to the increasing checks from the German Customs the price of the goods which are allowed to be exported with approbation of the Customs are more expensive now. There are also some real or online Asian shops in German’s big cities where you can buy the normal Asian foods like Yachaoonline.com (http://www.yachaoonline.com) or Caishichang (http://www.caishichang.de). But they are always more expensive than in China. If you need something special you have to bring it with you for emergency.
