 We don't tell them what to do, but we recommend them how to use the good source of research and good source of data from the survey to make the decision. In support of the Sustainable Development Goals, the United Nations has called for a data revolution. Vietnam, together with UNU Wider and its partners, have established data sets charting the country's rapid development. This series shares some of the lessons learned. VAS data is very unique and very comprehensive. It covers many aspects, a rural household, from the living, from production, and from the social enterprise. Social issues and also rural enterprise. InSAR goes to the field and collects the data. And sometimes we go to the field with them together to understand more about the situation in the reality, and it will help us to better understand the data afterwards when using the data in the analysis. Every round of survey we have the descriptive report and number of in-depth reports. We choose in-depth reports based on the hot issues in the rural society, or the issue we think will have big influence for rural development in the future in Vietnam. Based on the in-depth reports, we build some policy brief. As the research is very evident, the research not exactly tells the policy what the government should do, but we make some policy implications. And the policymaker will make consider of implementation of the policy we are recommending. The research we base on evidence. So it's very confident and it's very trustworthy for the policymaker when they are making policy for rural development in Vietnam,
