Yunshu Xue, I am focusing on eco-friendly behaviour change in Environment management and also the WEVALUE method application in sustainable development. Via different level of field work, it could bring more deep understanding of the method we used and problems themselves. Out of academic life, I am a soccer player as well. I hope in future the sustainability concept could be set in every field in our human life. Now I am doing some researches on Waste Sorting Policy Impact & WS behaviour change at communities level.
