This book is based on China's poverty alleviation work and combines social work expertise with anti-poverty research to provide a blueprint as a reference for preventing poverty return in the post-2020 era, promoting rural governance, and effectively linking poverty eradication and rural revitalization. Through a two-year participatory cooperation, the book, taking the targeted poverty alleviation pilot project named "Warmhearted Home Delivery" in T District(Xiamen City, Fujian Province) as a case study, finds that social work against poverty among the deeply impoverished needs to base on a "fact-ethic" two-dimensional perspective integrating risk with ability to achieve the trinary combination of the population classification to prevent the risk of returning to poverty, the exploiting the potential of families to solve the living difficulties, and the environmental-supported community multi-participation assets. This book is the first professional book in China that systematically describes how to do a good job in poverty eradication and poverty return prevention for people with deep poverty. This book records the time, demonstrates the academic achievements, and focuses on people's livelihood.
