Six hundred years ago, Huang Gongwang, a painter from the Yuan Dynasty, painted Dwelling in the Fuchun Mountains based on the landscape on both sides of the Fuchun River. In preparation for the 2022 Asian Games, Fuyang is constructing a new city in full swing. Against this backdrop, The Warmth of Spring River tells the story of four brothers taking turns to take care of their mother who suffered from dementia after a stroke by the Fuchun River in Hangzhou. The four families face the test of family affection and life, and the story unfolds slowly like a scroll through the changes in the seasons.
