The purpose of this study was to describe the basic features of two major variables and to explore the relationship between them. The first variable is the informal social support accepted by Xiagang Zhigong（the Laid-off workers），the unemployed workers with Chinese characteristics. The second one is the job seeking behaviors. A questionnaire survey was used to gather data. It was found that the informal social support Xiagang Zhigong got was not sufficient and that most of them got nothing. Concerning their job seeking behaviors，informal contacts were most frequently used to find jobs，followed by formal channels through the government and direct applications for jobs by themselves. On the hypotheses，it was found that the more informal social support Xiagang Zhigong obtained，the more likely they would start more job seeking behaviors. Some valuable information was found in the study. Compared with the unemployed in western countries，Xiagang Zhigong were less likely to find jobs in the market. Social support theory，systems theory and empowerment were useful in explaining the relationship between informal social support and job seeking behaviors of Xiagang Zhigong. Traditional value，resources，individual ability，“face” idea and the quality of service might have something to do with the features of the two variables. Finally，recommendations were made for Xiagang Zhigong，service agencies and government.
