The impact of culture shock can vary from person to person. There can be significant differences because some people may be better prepared to enter a new culture. Four factors which play into these are personality, language ability, length of stay, and the emotional support received.

　　It is logical to think that when people are deprived of their familiar surroundings they will feel disoriented. One solution some have found is to bring a few small reminders of home. Pictures, wall hangings, favorite utensils, and keepsakes(纪念品)are all good candidates to make things feel more familiar. Another helpful activity is to establish little routines that become familiar over time. Even better is fitting things that were part of the regular routine back in the home country into the routine established in the new culture. This will make people feel more at home.
