Six hundred years ago, Mr. Huang Gongwang, a painter of the Yuan Dynasty, painted "Dwelling in the Fuchun Mountains" with the scenery of both sides of the Fuchun River. In preparation for the 2022 Asian Games, Fuyang is working feverishly on the construction of a new city. Against this backdrop, "The Warmth of the Spring River" tells the story of four brothers in Hangzhou, on the banks of the Fuchun River, in four seasons. Taking turns to take care of their mother, who has suffered a stroke and lost her mind, the four families are faced with the trials of love and life, which unfold like a scroll through the changing seasons of the year.
