I am coming to shenyeng for study, from Africa tropical how could i prepare for staying long?

You are from tropical countries, so it may takes you sometime to adapt yourself to the cool climate of the city, especially the bitter coldness in winter. You need to pack some long-sleeved shirts, overcoat, jackets and down jacket. Boots are also necessary in winter. Well, you do not need to bring so many clothes, for you can buy it after arrival. BTW, learning some simple Chinese also helps a lot.
