Taking overseas Chinese and compatriots from Hong Kong，Macao and Taiwan as subjects，through the analysis of 1052 interview materials，we found that：first，culture shock and reverse culture shock exist widely among the research objects，and the degree of culture shock is higher than that of reverse culture shock，and there are big differences between different groups；second，cultural shock is mainly manifested in “language barriers”，“living habits”，“social systems”，etc.，of which “language barriers” are the primary factor；third，reverse cultural shock is mainly manifested in “electronic payment”，“thinking logic”，“living environment” and other aspects，among which “electronic payment” is the primary factor；fourth，the research subjects usually adopt “active integration into local culture”，“communication”，“self-consciousness adjustment”，“participation in social activities” and other strategies to deal with culture shock，and adopt strategies such as “seeking help”，“seeking support”，“self-mind adjustment”，and “social network reintegration” to deal with reverse culture shock.
