General Secretary Xi Jinping has talked about homesickness on many occasions,pointing out that regional development should “retain homesickness”.From a philosophical point of view,the change from traditional homesickness to modern homesickness and then to retaining homesickness is a metaphor of the evolution of the relationship between man and man,man and nature.Modern homesickness not only contains the nostalgia for the hometown environment and culture embodied in traditional homesickness,but also contains worries and reflections on blindly pursuing modernization.From a realistic point of view,homesickness,as a cultural symbol,is a signpost and lighthouse for people to return to their spiritual homeland,and is also a barometer and thermometer for the development of a region.Rural revitalization is not only a material revitalization,but also a cultural revitalization.On the one hand,material and cultural revitalization creates conditions for “retaining homesickness”.On the other hand,“retaining homesickness” also requires the coordinated development of material and culture.
