The Yangtze River,as the"mother river",is one of the irreplaceable cultural archetypes of the Chinese nation.Its importance can be examined interdisciplinary through a series of aesthetic images and its aesthetic spirit.The"vast"Yangtze River is not only one of the most representative aesthetic images but also contains the spirit of harmony that is highly compatible with Chinese traditional aesthetics.On the one hand,the deep meaning of this aesthetic image can be revealed in multiple dimensions through the cultural imagination of dif-ferent disciplines such as aesthetics,geography and natural history.On the other hand,its aesthetic spirit can be systematically interpreted in terms of social,world,and values.Based on the contemporary context of the construction of the Chinese national community and national rejuvenation,this aesthetic image and its aesthetic spirit have positive enlightenment significance.
