Hi I am leaving for Changchun in last of this August for study...

First, transportation. The city buses only have Chinese characters. Do make it clear where to get off. When taking a taxi, show the destination with Chinese characters to the driver, or they will refuse to accommodate you. Secondly, food. Chinese food are great, but most of the restos have no English menu. Luckily, some have pictures. Probably you can order according to the pictures.

Suggestions:
1. be polite to others and they will be more friendly to you.
2. say many "thanks" (Xie Xie), then people would like to help you more.
