Every "root" would get 3 recruit cards after their own investigation, then cards could be promoted to another 3 qualified people who were willing to accept questionnaires. And this process would go on till the sample size was accomplished. χ(2) test, rank correlation and contingency coefficient would be applied for the statistical analysis.
