I just met a friend of an American student studying in China and got together with two roommates. Do you want me to bring some friends? Do I need to prepare anything?
Take money with you. Foreigners sometimes hold parties or invite people to join the AA system. This is what I read in a book. I don't know exactly. Anyway, take it just in case … and maybe bring a gift or something … it may be better to put on your formal and beautiful clothes at last.
