The film is divided into four parts, namely, "Those who fall away think about their trees", "Those who have luxuriant branches and good birds inhabit the "Pull up trees to find roots, dead woods in spring", "green trees form shades, and be customary", showing the important role of banyan trees for people and nature. However,people tend to ignore these things that are inconspicuous but can be seen everywhere that can have a huge impact on our lives.
